Police have launched a murder investigation after a 25-year-old man was shot dead outside a pub in Clapham.

Emergency services rushed to the scene shortly before 10pm on Monday following reports of gunshots being fired on Willington Road, Clapham.

Despite the efforts of paramedics, a 25-year-old man was pronounced dead at the scene.

The victim’s family have been made aware and continue to receive support from specialist officers.

Shortly after the shooting, a man attended hospital with a gunshot wound.

Met Police said they were awaiting an update on his condition as he remained in hospital.

The man, aged 22, has been arrested on suspicion of murder.

Police remained at the scene on Tuesday, with a cordon in place near The Landor pub, at the junction of Willington Road and Landor Road.

Residents said they heard several loud bands before hearing sirens as emergency services rushed to the scene.

Photos from the scene show a forensic tent set up, as officers monitor a police cordon.

Floral tributes have also been placed near to the pub.

One local resident said he heard three gunshots on Monday evening and described seeing someone run out of The Landor pub and shout “call the police”.

The man, who did not wish to be named, said he saw a moped and white car drive off before the police arrived.

He said that women could be heard “screaming and crying” outside.

A 26-year-old woman living nearby said she heard four gunshots and initially thought it was the sound of a car backfiring.

She said: “There was a guy lying on the ground, lots of blood around him. There were loads of people around him, I went and helped.

“I work in healthcare and I went and helped assist.”

The woman added that when the police arrived, the crowd of people helping stood back and let them take over.

She said there was a significant emergency response with armed police officers at one point.

Witnesses have said that the shooting was a case of “mistaken identity”, with a family member of the victim telling the Metro that he had been dropping off his girlfriend when he was shot.

The said: “We are shattered by this. I can’t believe it. I was due to see him at a birthday party on Saturday. We are devastated.”

A former school friend of the man who died said: “He was a lovely, bouncy sort of guy. We used to play together in the play park just 100 metres from where he died.”

Another woman at the scene claimed the victim was in the “wrong place, wrong time”.

One local told London Now that she is considering moving out of London after the shooting.

She said: “It’s sad what happened, that someone lost a life. I told my daughter this morning that I want to move.”

A staff member from the Landor pub said: “The police have the footage. The shooting was nothing to do with the pub, it was outside.

“We have never had trouble here, but lately this area of Clapham has got worse. People seem to have lost their minds.”
