Police were questioning a man tonight after another man was gunned down outside a fast-food restaurant.
Daniel Smith, 22, died outside a branch of KFC in Harrow Road, Paddington, north west London, in the early hours of May 22.
Investigators believe he may have been mistaken for a gang member or caught in the cross-fire between feuding groups.
A Metropolitan Police spokesman said a 23-year-old man was arrested on suspicion of murder earlier today.
Mr Smith, an electrician, lived with his mother and two sisters on the Mozart Estate. He died from a single gunshot wound.
Two 21-year-old men questioned in May have been released on bail until August pending further inquiries.
