A child is in serious condition and three adults have been injured after being shot near a restaurant in north-east London.
Police were called to Kingsland High Street, in Dalston in Hackney, at about 21:20 BST on Wednesday, after reports of gunshots.
Officers, including firearms specialists, and the London ambulance service attended the scene, the Metropolitan Police said.
The four victims were found with gunshot injuries and were taken to hospital in east London, the Met added.
The force said the child remains in serious condition and that it is awaiting further details of the other victims’ conditions.
No arrests have been made and an investigation into circumstances around the incident has been launched.
Deputy Assistant Commissioner Matt Ward said Londoners “will be shocked” by the incident.
“Our thoughts go to all those affected,” he added.
“Fast moving enquiries are under way and we will update as soon as we can. If anyone has any information, please contact us.”
A London Ambulance Service spokesperson said it treated the three adults and the child at the scene before taking them to a major trauma centre.
Passer-by Ayo Adesina told the BBC: “I arrived maybe about four, five, six minutes after it happened.
“People were just silent, like someone was trying to help… people just seemed stunned and trying to work out what was happening.”
He said Kingsland High Street was a popular area and it was “very reckless for someone to have done”. “Literally anyone could have got shot,” he added.
