Police are using the first anniversary of a fatal stabbing to make a renewed for witnesses.

Sunday, October 20, will mark one year since 28-year-old Teon Palmer was murdered at the junction of Montagu Road and Goodwin Road in Edmonton.

Mr Palmer, from Lower Edmonton, was stabbed in the chest and pronounced dead at the scene.

It is believed that a car belonging to Teon had all four tyres slashed in the moments leading up to the assault.

Seven black males, described as wearing hooded tops or jackets, were seen making off from the location.

Police will be returning to the area between 9pm and midnight on Sunday to appeal for witnesses, information and assistance in the investigation.

They will also be offering a substantial reward of up to £20,000 for information into the murder of Mr Palmer.

A 23-year-old man was arrested on suspicion of murder on October 25, 2012, however, he was subsequently released with no further action.

Detective Chief Inspector 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."

Anyone with information is asked to contact the incident room on 020 8345 1570 or call Crimestoppers on 0800 555 111.
