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.
It is understood that people from 50 surrounding properties were asked to leave their homes during the incident.
Lewisham Council said in a social media post today that the Salvation Army and a local church provided rest centres for displaced residents.
Detective Superintendent James Derham from the Metropolitan Police said: “I want to say a big thank you to those in Catford for their patience and assistance over the last few days while officers worked around the clock to resolve this incident safely.

“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,” he said.
“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.”
He added: “Our officers worked closely with partners, including the local authority, to ensure any disruption to residents and those travelling through Bellingham and Catford was kept to a minimum. I extend my gratitude to other emergency services that remained on standby throughout the duration of the incident, ready to offer support as needed.
