WATCH: CCTV footage shows gunman shooting at then chasing victims

Dramatic CCTV footage of a gunman firing a gun as he chases his victims down the street has been released by police.

The clip shows a group of three men walking along Tulse Hill in Brixton, south London, when the pillion passenger on a passing moped jumps off the bike and opens fire.

As the trio flee, the gunman chases them, brandishing the weapon, and takes a second shot. He then runs back to the bike, which drives off towards Norwood.

One victim suffered a gunshot wound to the thigh in the attack, which happened at around 7pm on Sunday February 7.

Scotland Yard said the rider of the moped was wearing a light-coloured helmet. The gunman was wearing a black, full-face helmet with white flashings and dark trousers with white stripes on the leg.
