A new appeal has been issued about the unexplained death of a man in Palmers Green five years ago.

Kester David, 53, was found in an archway behind a Travis Perkins building in Bloomfield Lane, Palmers Green, on Wednesday July 7, 2010.

The part-time bus driver and DJ was last spotted on CCTV entering the shop at a Texaco service station, in Lordship Lane, Wood Green, on the night of his death at 9pm.

Mr David used to live in Russell Avenue, Wood Green, and died the day after he turned 53.

Detectives are now making another appeal to trace witnesses they believe could hold the key to finding out who killed Mr David.

Two men, one in a grey hoody, were spotted on July 7, 2010, squeezing into an alleyway near Maple Leaf Court, on the other side of the railway line to where Kester was found at approximately 2.30am.

Enfield Independent:

In order to reach where Kester was found, they would have had to then scale anti-climb fencing next to the railway line, cross the line and tackle another anti-climb fence.

Nevertheless, detectives are keen to trace these men in case they have any information useful to the investigation.

Two white men of around 5ft 8ins to 5ft 11ins tall and of average build, were seen walking across Morrison's car park at 3.45am that day.

They walked towards charity recycling bins in the far corner. There was also an anti-climb fence separating Morrisons' car park from Travis Perkins yard next door.

Enfield Independent:

Detective Chief Inspector Noel McHugh, of homicide and major crime command, said: "Were these two separate groups of men? Or in fact the same people seen on two occasions that night?

"Even with the passage of time, I believe those individuals will recognise themselves from their actions, location and the significant appeals we have made around Kester's death.

"I would like to make it clear that my priority is investigating the circumstances of Kester's death. I am really keen to speak to you - you may not realise that you hold important information that would assist my investigation.

"Do you know anything or do you recognise yourself from the information given?"

Officers are also still anxious to trace Kester's missing mobile phone.

His Blackberry Curve 8520 has never been found. It was last switched on on July 14 and 15 2010 in the general vicinity of Wood Green shopping centre and on July 22 near Whittington Hospital. It would have been locked so no calls could be made. It has not been used since.

The IMEI number of Kester's phone is 35943003791209.

Enfield Independent:

Detectives are also reiterating previous appeals made during the course of the investigation.

Two days before Kester's death, a relative called Kester on his mobile phone but a man who was not Kester answered the phone. Police are also still keen to trace this person and if it was perhaps one of his work colleagues.

Officers are also still anxious for the author of an email sent to police to come forward.

Two weeks after Kester's death, police from an Enfield Safer Neighbourhoods team received an email from someone calling themselves 'Sharon Clarke', who appeared to have known Kester well.

This person claimed to know who was responsible for Kester's death. Police urgently need to hear from this person.

Anyone with information should call 020 8785 8099 or Crimestoppers anonymously on 0800 555 111.
