A man has been arrested after police spent more than 50 hours negotiating with someone alone in a property with a gas canister.
There had been “significant fears” that the man in the property on Daneby Road, Catford, south London, would harm himself or others, police said.
A man, 26, has been arrested on suspicion of making threats to cause criminal damage with intent to endanger life.
He required hospital treatment for a foot injury after he was bitten by a police dog and remains in hospital.
Detective Superintendent James Derham said: “I absolutely do not underestimate the impact this has had on the day-to-day lives of residents, especially those who were displaced from their homes.
“Our specialist and local officers used all their skills to deal successfully with this extremely sensitive and complex matter in a thoroughly professional manner. This involved the deployment of crisis negotiators to communicate with the man inside the address and highly trained firearms officers to ensure the safety of all involved.”
