A seventh man has been arrested over the murder of an electrician who was killed in an apparent case of mistaken identity in west London.
Daniel Smith, 22, from Paddington, was shot outside a fast-food restaurant at the southern end of Harrow Road in May.
A 28-year-old man arrested on Friday night is being quizzed by detectives.
Another man, 26, arrested in south Kilburn on Friday also remains in custody. Five others questioned over the murder were bailed until October.
Detectives have offered a reward of up to £20,000 to help catch Mr Smith's killer.
Mr Smith, who lived with his mother and two sisters, had been out with a friend before stopping at a KFC in Harrow Road, Paddington, on his way home.
Eyewitnesses said he was shot as he walked back to his car. He managed to stagger into the takeaway but collapsed and died later in hospital.
