POLICE hunting the murderer of Natasha Derby are examining coincidences with a shooting a few years ago in London.

Officers are talking to the Metropolitan Police after it was revealed the DJ at the Summer Jam event in High Wycombe, partly organised by Natasha, had been the DJ at another event in London when someone was shot.

Natasha was killed on September 4 at the Multi-Racial Centre in St Mary Street.

Officers from Operation Trident the Met's black on black gun crime task force have been advising Thames Valley Police on engaging with black communities and hunting down the killer.

Detective Chief Inspector Andy Taylor said: "What we are doing is trying to explore all possibilities and there was a shooting going back some time ago down in the London area.

"We have made enquiries in respect of that principally because it was the same DJ that was playing at the same event. But there is nothing in that that makes my hairs stick up on end and think we need to be getting on to this quickly.

"We have made a number of contacts with Operation Trident and have tied in with them quite tightly and we are moving through and identifying more and more people at the event.

"We are up to about 65 or so now but there is still some way to go.

"They are telling us more about the people that were there and we are getting much more of a focus around the Reading and Slough areas, which is what we always thought."

Last week a reward of £10,000 was offered to catch her killer.

Officers are keeping an open mind on the killing but think Natasha may just have been in the wrong place at the wrong time.

Despite the progress being made in the investigation officers are still in the dark about events surrounding the shooting.

DCI Taylor said: "We do not know exactly what happened.

"Although people have seen Natasha fall to the floor and saw the gun go off, they have not seen anyone with a gun.

He added: "The actual number of people from the Wycombe area was fairly small."

"The black community in High Wycombe has been absolutely marvellous,"

Officers are still considering an appeal on BBC Crimewatch but have no plans of launching a nationwide appeal yet.

"We are getting names of people we are sure were there. With Crimewatch there is a danger we may not be able to separate the wheat from the chaff."
