Police will make an appeal on Crimewatch tonight to find the killer of a bouncer who was shot as he shielded a woman outside a nightclub.

Kolawole Ojo Babadiya, 28, died after he was shot outside Bar SW8 in Wandsworth Road on July 15 at around 1.37am.

He received a single gunshot wound to the head and was pronounced dead at the Royal College Hospital later that morning.

The BBC programme includes an emotional interview with members of Kolawole's family, and an interview with Michael Blair, the proprietor of the bar.

Investigating officer Detective Inspector Tim Neligan of Trident will also make a fresh appeal for witnesses and anyone with information to come forward.

The Met Police is offering a £20,000 reward for information leading to the identification, arrest and prosecution of those responsible for Kolawole's death.

According to witnesses the gunman was wearing a long, dark coat when he opened fire using a high-powered weapon - which he had difficulty controlling.

He was standing approximately 30 metres from the club entrance and produced the weapon from under his coat.

Officers later recovered 17 cartridge cases from the scene.

Det Insp Tim Neligan said: "We are keeping an open mind as to who the gunman was aiming at; we believe the gunman could have been aiming at those persons inside or outside the bar SW8 or the bar itself.

"We have no doubt that there are people within the community who know who is responsible for Kolawole's murder and I would ask them to find the courage to come forward.

"I wish to offer my personal assurance that all information will be treated with the strictest of confidence.

"Our sole concerns are catching those responsible and taking guns off the streets so that no other families have to go through such a devastating loss."

Anyone with information should call the Trident incident room on 020 8247 4554 or Crimestoppers anonymously on 0800 555 111.

Crimewatch is on BBC One tonight at 9pm.
