Police were questioning a sixth man today over the murder of a fast-food restaurant customer caught up in a gang shooting.
Daniel Smith, 22, died outside a branch of KFC in Harrow Road, Paddington, north west London, after fetching food for his family.
Metropolitan Police officers held a 26-year-old man on suspicion of murder at a property in South Kilburn at 3am today.
The suspect was the sixth to be arrested over the unexplained shooting in the early hours of May 22.
Investigators believe Mr Smith may have been mistaken for a rival gang member and released CCTV images of three suspects.
The electrician lived with his mother and two sisters on the nearby Mozart Estate. He died from a single gunshot wound.
A reward of up to £20,000 is on offer for information leading to an arrest and prosecution.
Police have offered two potential witnesses protection if they come forward with information.
They want to speak to a black woman, aged in her early twenties and wearing a distinctive baseball cap with the letter P on, seen at KFC.
The second potential witness is a white man with brown hair and glasses seen carrying a briefcase near the takeaway.
Five men aged between 21 and 30 have been questioned on suspicion of murder and released on bail pending further inquiries.
