POLICE are offering a £20,000 reward to help catch the killer of a man murdered four years ago.

Teon Palmer, of Lower Edmonton, died after having his car tyres slashed in Goodwin Road on October 20, 2012 at 11.10pm.

Men wearing hooded tops or jackets were seen running away just after the attack.

The 28-year-old died at the scene.

Detective Inspector John Marriott, from the Homicide and Major Crime Command, said: "Although four years have passed, we remain committed to finding those responsible for Teon's murder.

"I strongly believe that there are people, who were not there that night, who know who stabbed Teon. I would urge them to contact us.

"It is also possible that allegiances have changed, and that someone, who may not have wished to speak with police at the time, may now be encouraged to do so. A substantial reward remains in place.

"Teon's family deserve to know what happened. I would ask anyone who is yet to speak with us to contact the incident room."

Four men arrested in 2012 were released with no further action.

Anyone with information is asked to contact the incident room on 020 8345 1570; if you wish to remain anonymous call Crimestoppers on 0800 555 111.
