An innocent bus driver shot dead in south-west London was not the intended target and was "in the wrong place at the wrong time", the Metropolitan Police have said.
Auguste-Marie Bile-aka Amoa was shot outside The Landor pub in Clapham shortly before 22:00 BST on 10 August. The 25-year-old died at the scene.
A 22-year-old man was arrested on suspicion of murder on the same day and later released with no further action following police enquiries. No further arrests have been made.
Police have released CCTV footage of the moments following the shooting and Crimestoppers has offered a £20,000 reward for information leading to identification and conviction of those responsible.
Two CCTV clips have been shared by detectives, which show a moped turning right from Landor Road into Willington Road, where the shooting took place, at 21:56, then leaving the area along Kings Avenue at 21:57.
Plea for justice
In a statement, his family said "nothing can bring back his smile or fill the space he has left in our lives" and appealed for any information to help "establish the truth and secure justice for him".
"He was an amazing young man full of love, kindness and an enthusiasm for life," they said.
"Bile-aka was a dedicated bus driver, a job that he loved and was so committed to. Bile-aka touched so many hearts, and the pain of losing him is impossible to put into words.
"But if you know something, you may be able to help us find the answers we so desperately need.
"Please stand with us in our grief, honour Bile-aka's memory, and help ensure that justice is served."
Det Ch Insp Claire Guiver, leading the Met's investigation, said: "The loss of Bile-aka continues to hurt his family as they are left with a void that cannot be filled as a result of this tragic incident.
"There is someone out there who knows what happened that night and we are urging those individuals to find it in their heart to come forward.
"No matter how small you think the information is, please speak to us. It could be exactly what we need to find those responsible."
A force spokesperson said: "While officers are keeping an open mind as to the motive, investigators believe Bile-aka was simply in the wrong place at the wrong time and was not the intended target of the attack."
