Seven men have been bailed over the death of Oliver Tetlow who was gunned down in Harlesden, north London last week. The 27-year-old was shot on Church Road in a drive-by said to have been provoked after a feud between London rappers Nines and Cbiz turned violent.

The men – aged between 18 and 29, one of whom was Cbiz – were arrested on suspicion of either robbery or murder and have since all been bailed pending further enquiries until dates in either May or June.

The incident was even discussed in the House of Commons during Prime Minister's Questions when Brent Central MP Dawn Butler asked David Cameron if he would meet her to discuss gun crime in the capital.

The PM agreed to, adding Tetlow's murder was a "tragic case and our hearts go out to the family of the person she talked about".

He added: "But we have seen a reduction [in gun crime]. We have seen more active policing in our communities, better intelligence policing in terms of dealing with gun crimes and we must keep that up. "

Investigating officer detective chief Inspector Mark Lawson said officers would return to the scene of the killing on Wednesday night in the hope of finding more eyewitness accounts.

"This evening (March 16) my detectives will return to the scene along with local officers to speak to people and encourage more witnesses, and anyone with information, to talk to us," Lawson said. "Today, I am specifically appealing for the driver of a white transit van that was parked in Church Road, close to where the shooting took place, to come forward.

"I believe the driver was sat in the driver's seat at the time and it is possible they could have witnessed something. I would again like to reassure anyone worried about coming forward that they will be treated with the utmost sensitivity."
