A man who barricaded himself inside a house in West London is being held by police after they forced their way into the property.
The Metropolitan Police said officers gained access to the property in Wood End Lane in Northolt at about 8.10pm on Sunday, (23 October) bringing a three-day standoff to an end.
The suspect has been arrested on suspicion of the cultivation of cannabis, affray and offences under the explosives act, Sky News reports.
Officers had been called to the house during the early hours of Friday (21 October) morning following concerns that a man who was alone, may have had a stockpile of "petrol and combustible" material.
Around 80 people in the surrounding area were evacuated as a precaution, and an area with a radius of 200m was sealed off as police attempted to negotiate with the man.
Negotiations with the man, who is in his forties, were unsuccessful, prompting police to force entry.
It was reported that the man owns up to four Rottweiler dogs, which had also impeded the efforts to gain access to the property. Family members have said they believe the man has recently had a "breakdown."
Chief Superintendent Paul Martin said: "I am really pleased that this incident has now ended, and importantly ended without anyone coming to harm. Our key priority throughout this was to get the man out of the address safely as we had growing concerns about his well-being and believed him to be in crisis.
"After attempts to negotiate over a number of days did not work, we used specialist officers to work out how we could gain entry to the address as safely as we could. They did that this evening."
A search of the house is being conducted to ensure it is safe as the evacuated neighbours return home, BBC News reports.
Police had said there was no suggestion the incident was terror-related or linked to any ongoing police operations or investigation.
