Detailed guide explaining how an assault offence charge is made by police in England and Wales, including reporting, investigation, charging decisions, types of assault charges, legal rights, time limits, and what victims and suspects can expect at each stage.

In England and Wales, an assault offence charge is a formal allegation made by the police that someone has committed an act of unlawful violence or threatened violence against another person. This article explains how such charges arise, the legal and procedural steps police follow, what offences may be charged, how charging decisions are made in conjunction with prosecutors, the rights individuals have during the process, and practical considerations for victims and those under investigation. The information reflects current guidance used by police forces, the Crown Prosecution Service (CPS) and courts.
What Is an Assault Offence?
“Assault” is a broad term covering several criminal offences involving the application or threat of unlawful force:
- Common assault: causing another to fear immediate unlawful violence or applying minor force.
- Battery: the actual infliction of unlawful force.
- Assault occasioning actual bodily harm (ABH): causing more than transient or trifling injury.
- Grievous bodily harm (GBH): causing serious injury.
- Assault on emergency workers or police officers: where the victim is a designated worker performing duties.
Police assess evidence and circumstances to determine the most appropriate offence or combination of offences to charge, guided by CPS charging standards. Serious injury or specific contexts such as domestic violence or use of weapons often warrant charges beyond common assault.
Step‑by‑Step: From Report to Charge
1. Crime Report and Recording
The process usually begins when someone reports an assault to the police. Reports can be made online, by phone (via the non‑emergency 101 or emergency 999) or in person at a police station. The police then record the incident as a crime and start an investigation, which may include taking statements, contacting witnesses, and gathering physical or digital evidence such as CCTV or medical records.
2. Investigation Phase
During the investigation, officers:
- interview the alleged victim and witnesses;
- obtain medical or forensic evidence;
- assess whether there are reasonable grounds to suspect a named individual committed an offence; and
- decide whether to arrest a suspect.
A suspect may be arrested if there are reasonable grounds to suspect they committed the offence. In some cases, the suspect may be invited to attend a voluntary interview at a police station without arrest. Arrested persons are afforded legal rights, including the right to consult a solicitor and to remain silent.
Police have defined limits on how long they can detain someone without charging them (generally up to 24 hours, and in serious cases up to 96 hours with authorisation).
3. Charging Decision
Once sufficient evidence is collected, the police must decide whether to charge the suspect. The charging decision must satisfy two main legal tests:
- Evidential sufficiency: whether there is a realistic prospect of conviction based on the available evidence; and
- Public interest: whether prosecuting the case is in the public interest.
For the least serious assaults, such as common assault where this is appropriate, police can make the charging decision themselves. For more serious offences or cases requiring higher sentencing powers, police refer the file to the CPS for a formal charging decision. The CPS also provides early advice during complex investigations if requested.
Charging authority explains why a particular offence is selected, and in some cases offences recorded initially by police may be amended before formal charge to better reflect the evidence and legal elements.
4. Out‑of‑Court Disposals
Not every assault results in a formal charge. For less serious cases where prosecution is not considered necessary, police may use an out‑of‑court disposal such as a warning or a caution. A caution is not a conviction but is recorded and can have implications for background checks and future legal matters.
Types of Assault Charges and Context
Common Assault and Battery
These are typically summary offences (heard in the magistrates' court) for less serious conduct. Proceedings for common assault generally must begin within six months of the offence occurring, unless a more serious offence is appropriate.
More Serious Assaults
Assaults causing actual bodily harm or grievous bodily harm are either‑way or indictable offences. They carry higher maximum sentences and are referred to the CPS for charging decisions, regardless of whether the suspect is in custody or released under investigation.
Assaults on Emergency Workers and Police Officers
Assaulting an emergency worker, including a police officer performing their duty, is recognised as a specific category of offence. The CPS has updated charging guidance on these matters, using offences that reflect the seriousness of the conduct and give courts adequate sentencing powers. For lower‑level conduct against officers, police may charge the statutory offence of assaulting a constable in the execution of their duty or, where appropriate, an assault on an emergency worker. For more serious harm, prosecutors use ABH or GBH charges.
Interaction Between Police and Prosecutors
Police and prosecutors work closely, especially when evidence is complex or when the offence carries significant penalties. Police may seek pre‑charge advice from the CPS to confirm the validity of potential charges. For intermediate cases, CPS lawyers can give charging authorisation via phone or secure digital systems. For very serious cases, the CPS takes overall responsibility for the charging decision.
Rights and Safeguards
Individuals who are suspected or charged with an assault offence have specific legal rights, including:
- the right to legal representation throughout the process, including at interviews;
- the right to consult a solicitor before answering police questions;
- the right to be informed of the charge and the court date; and
- protection from unfair detention beyond statutory limits.
Those reporting assault also have rights as victims to updates about progress and an explanation of decisions not to charge, although police workload and investigative complexity may cause delays.
Statutory and Procedural Time Limits
Statute imposes time limits on prosecuting certain assault charges. Summary offences such as common assault ordinarily must be brought within six months of the offence. More serious assaults (e.g., ABH, GBH) have no statutory time limit, meaning a report can be made and a prosecution pursued long after the incident. However, reporting promptly maximises the likelihood of effective evidence collection.
Practical Considerations
For Victims Reporting Assault
Victims should provide detailed accounts, preserve evidence (such as medical reports or photographs), and keep records of reporting and communications with police. Prompt reporting can be crucial, especially for summary offences with time limits.
For Suspects or Those Investigated
Those under investigation should consider seeking legal advice early, fully understand bail or release conditions, and engage with their solicitor about the evidence and possible outcomes. Even where a charge is anticipated, legal representation can assist in navigating interviews, bail considerations, and strategic defence planning.
Final Thoughts
An assault offence charge in England and Wales begins with a police record of a reported incident and progresses through investigation, evidence gathering, and a charging decision that may involve the CPS. Decisions are guided by legal principles of evidential sufficiency and public interest, with various assault offences reflecting different levels of harm and context. Police charging practice aims to ensure appropriate offences are selected and that procedural safeguards, rights, and statutory limits are respected throughout the process.
