A man involved in a stand-off with armed police was filmed hurling petrol bombs at officers.
The resident, who is understood to have called police himself, barricaded himself inside a house on Lintz Terrace, Burnopfield, County Durham.
An eye-witness told the BBC he saw “up to seven” explosive projectiles thrown.
Durham Constabulary said officers entered the property at 11:30 BST and a 47-year-old man has been arrested for threats to kill and criminal damage.
More than a dozen officers, including negotiators, had been at the scene since Tuesday afternoon.
No-one was injured.
