POLICE are launching a fresh appeal to find the killer of an officer on the 25th anniversary of his death.

Jim Morrison, 26, started life on the force at Bow Street Station, but was off duty in Covent Garden on December 13, 1991, when disaster struck.

On the night of the incident, Jim had gone to the Nell Gwynne pub at Bull Inn Court for around an hour from 8pm, before deciding to head home.

However a group of bag snatchers had recently been working in the area and that night a handbag had been stolen from the Maple Leaf pub.

Jim was seen getting involved in a struggle with a man outside the Transport Museum at around 10pm.

The suspect broke free and a chase ensued which ended tragically with Jim being stabbed, before the man fled.

At the time, he was described as being of Algerian or North African origin, 5ft 10ins tall and aged approximately 27 to 30.

He was of medium build, clean shaven and had dark collar length hair, with distinctive tight curls at the front.

He was wearing a waist length tan or brown leather jacket.

Renowned for his dedication to duty and flair for dealing with street crime, Jim sadly left a widow, Victoria.

Despite extensive inquiries and a number of arrests over the years, his murderer has never been brought to justice.

The Met is also raising its reward from £20,000 to £30,000 for any information leading to the identification, arrest and prosecution of the person responsible.

Police believe there are still people who hold vital information about who is responsible for Jim's murder.

A close friend of Jim, Met Police Sergeant Colin Geddes said: "Jim and I met at Bow Street Station early in our service.

“We were best men at each other's weddings, he was a fun man to be around and I had a lot of respect for him as a colleague.

"His death has left a tremendous gap in the lives of those who knew and worked with him. He is hugely missed."
