A FRESH appeal has been made to find the person who shot dead a policewoman in Victoria 25 years ago.
WPC Yvonne Fletcher was fatally injured at St James's Square in 1984 during a demonstration outside the Libyan Peoples' Bureau.
A murder investigation has remained open since her death.
On Friday April 17, the 25th anniversary of her murder, friends and family together with serving and retired police officers gathered for a service in the square where she was shot.
They later moved to nearby St James's Church, in Piccadilly.
Commissioner Sir Paul Stephenson, who attended the service, said: "Yvonne's murder is a stark reminder of the huge risks police officers can face on a daily basis while doing their duty. "This tragic and unprovoked attack on someone who was working to ensure public safety remains an horrific event in policing history.
"We will never cease in our aim to identify those responsible."
Detectives have remained in regular contact with WPC Fletcher's family to update them on developments.
Following the restoration of diplomatic relations between the UK and Libya, a joint investigation by the Met police and the Libyan authorities was started.
Detectives have visited Libya several times to meet officials from the Libyan investigation team.
The Met hopes that officers will be able to return to Libya in the future so that they can progress the inquiry further.
