One man has been killed and another two seriously hurt in separate shootings in or near London clubs
Daniel Ross, 22, was in the Scala nightclub, King's Cross, when shots were fired in the early hours of Sunday. He died later in hospital.
His death is being investigated by Operation Trident, which specialises in shootings within the black community.
Two men survived a shooting outside the Fridge club in Brixton in the early hours of Monday.
Mr Ross is thought to have been on or near the dance floor on the middle floor of the club when he was shot.
The club's lights went on and the 850 to 1,000 people in the club at the time spilled out of the club through fire exits.
Scala attracts people from all over the country, and police want to speak to anyone who was inside and saw what happened.
Det Ch Insp Fiona Mallon, from Operation Trident, said: "Daniel's family are understandably distraught and very confused as to why their son was killed.
"I would ask anyone with information or who was in the club at the time to contact us."
She also asked anyone working in the club that night to get in touch in confidence.
Police said it was a rare occurrence as they work closely with the club on its licensing and security.
The victims of the shooting on Brixton Hill were found outside the Fridge shortly before 0500 BST on Monday, and were treated at the scene.
Both were taken to an unnamed hospital, where they were said to be in a serious but stable condition.
Six weeks ago Sharif Zaiden, 18, from Ladbroke Grove, was shot dead on the dance floor at the nearby Egg club in King's Cross.
