A man who died after police were called to a Bexleyheath disturbance was being detained by officers when he "rapidly" deteriorated.

A police watchdog investigation was launched in the early hours of Tuesday morning after the man was pronounced dead late on Monday night.

Officers had been called to Eversley Avenue to reports of a disturbance and found the man, in his 30s, at the house. It is reported there were concerns for his welfare.

The officers detained the man and called an ambulance. According to the Independent Office for Police Conduct, this is when the man's condition deteriorated.

Police at the scene administered first aid before the ambulance arrived and he was taken to a south London hospital where he later died.

IOPC officers have been taking accounts from Met Police officers who were at the scene.

Footage from body cameras worn by the officers is being analysed as part of the investigation, as well as CCTV footage.

Statements have also been taken from people living nearby.

IOPC regional director Jonathan Green said: “This is a tragic incident and my thoughts go out to family, friends of the man and to all involved.

“Sadly, he appears to have rapidly become extremely unwell, he died after being detained by the police and as such the circumstances require a thorough independent investigation.”
