A police officer responding to a stabbing has suffered burn injuries after getting caught in an explosion as he entered a flat in Lewisham.
Neighbours heard police say that a man had locked himself in a flat above a parade of shops at Batavia Mews, New Cross at 1.30pm on Friday.
As officers stormed in an explosion “like a bomb going off” rocked the neighbourhood with plumes of smoke billowing out of a top story window.
The police officer’s burn injuries are currently thought to be non-life threatening.
In footage posted to social media, a naked man could be seen sitting on a roof in front of the smouldering building as police urge him to come down.
A neighbour Olivia Johnson, 24, told The Standard: “I heard a police officer say the man looked himself in a room. The police dogs were sniffing around the area like two hours before anything happened
“Then it was kind of crazy, my flatmate saw the explosion just from our window. He said it was like a ball of fire coming from the window. It was loud like a bomb.
“Then this naked man jumped from the window and wouldn’t come down.
“The police helped him down but ages after they evacuated the rest of the building.”
Police said a man, aged 40, was arrested on suspicion of arson with intent to endanger life at the scene.
He has been taken to hospital as a precaution.
At this stage, the incident is not thought to be terror-related.
Road closures have been put in place around the scene.
A Met spokesman said: “At this early stage, the incident is not thought to be terror related and there is no evidence of drugs manufacture at the premises.
“Enquiries continue to establish the circumstances.”
