Police Offer Reward Over Stabbing
Police are offering a £20,000 reward for information about a fatal stabbing in north London on the first anniversary of the murder.
Teon Palmer, 28, died from a single stab wound to the chest following the attack in Montagu Road, Lower Edmonton, around 9.30pm on Sunday, October 20, last year.
Up to seven people were seen running away from where Mr Palmer died, but nobody has been charged over his death.
Family and friends will return to the scene, a year on, to hold a vigil for Mr Palmer.
Metropolitan Police officers will also be in the area between 9pm and midnight to appeal for witnesses.
DCI Neale Baldock, said: "It is almost one year since Teon's murder.
"I believe the key to this investigation is likely to come from within the local criminal fraternity or their associates.
"In the intervening period loyalties and allegiances may have changed, and I would appeal to anyone with information to come forward and speak to us."
Police believe Mr Palmer's car tyres were slashed in the moments leading up to the attack.
The seven people seen running from the scene are described as black and wearing hooded tops or jackets.
A reward of up to £20,000 for information leading to the identification, arrest and prosecution of those responsible is being offered.
Anyone with information is asked to call 020 8345 1570 or Crimestoppers anonymously on 0800 555 111.
