The region's most serious offenders have been locked away for more than 3,000 years.
Since the Major Crime Unit was formed in 2012, the tri-force collaboration between Cambridgeshire, Bedfordshire and Hertfordshire police have overseen offenders who have committed the most serious and horrendous crimes locked away for more than 3,000 years.
Detective Superintendent Jo Walker leads the unit and said: “Seeking justice for victims and their families is at the heart of what we do. The mix of skills and specialist knowledge of our staff and officers on the unit allow us to track down offenders and build cases to bring them before the court.
“It is not only the work of my officers and staff who play a part in dealing with these investigations. We work closely with colleagues and partners in many different departments across Bedfordshire, Cambridgeshire and Hertfordshire to deliver justice and reassure our communities.”
The tri-force unit is made up of more than 100 detectives and 70 staff who investigate all major crimes across the three counties. The offences they deal with include murder, manslaughter, stranger rape and kidnap and extortion as well as cold case (historic) offences. At any one time the teams are investigating up to 50 cases across the three forces.
The Major Crime Unit has worked on some of the most serious cases in Cambridgeshire and Peterborough since 2012.
