PSI – Police Staff Investigator

Police Staff Investigator (PSI) trainees solve cases, just like any other officer. The main difference is you’ll be focused on investigating crime rather than other elements of police work. There’s a comprehensive six-week, classroom-based introduction to complete first, and then a set period of mentoring and assessment as you get to grips with live work.

You’ll use your skills to determine which laws have been broken, devise and execute investigative strategies, and go on to prosecute offenders. Some cases you’ll work alone, others alongside other PSIs, police constables and detectives. On any day, you could be taking a statement, searching a premises, reviewing CCTV, interviewing a prisoner – even giving evidence in court.  

There’s a clear progression path, too. The team will support you as you study to become an experienced PIP1 investigator and to then diversify into other specialist investigation teams. You might even go on to enhance your skills further and become a PIP2 investigator, which means you can take on responsibilities like a detective constable and be ready to take on weightier cases.
