James Francis Hurley, 42, was sentenced to life imprisonment in 1989 after shooting an off-duty police officer during a bank robbery in Hertfordshire.
Hurley, who has been added to Scotland Yard's wanted list, escaped when he was being moved to Wandsworth Prison by bus in 1994.
A £10,000 reward is being offered for his capture.
On 14 April 1988 three men - Perry Wharrie, Charles McGhee and James Hurley - staged an armed robbery of a security van outside a Barclays Bank in Hemel Hempstead.
Mr Wharrie and Mr McGhee, armed with guns, approached the security van guard as he went towards the bank.
Hurley was acting as the getaway driver and was parked nearby.
Off-duty Hertfordshire Police Constable Frank Mason, 27, attempted to intervene in the robbery.
As Pc Mason grabbed one of the suspects and tried to arrest him he was shot in the back by Hurley.
He later died of his injuries.
Commander Andy Baker, of the Metropolitan Police's Specialist Crime Directorate, said: "We would like to appeal to anyone who has any information about the whereabouts of James Francis Hurley who escaped exactly 10 years ago on Monday.
"Hurley is a convicted murderer and armed robber who was involved in an incident in which an off duty police officer was callously murdered, while bravely trying to intervene in an armed robbery.
"We know that Hurley has friends and contacts in the UK and Europe and believe he may currently reside in the Republic of Ireland, particularly the area of Roscommon, and may travel to Spain.
"We believe Hurley may have adopted a new identity and tried to start a new life for himself, but you cannot leave your past behind."
Anyone with information about Hurley is asked to call Scotland Yard's Wanted hotline number 0207 233 4128 or contact Crimestoppers anonymously on 0800 555 111.
