A half-naked man was tasered after threatening police with a knife.

At 5.50pm on Saturday, police received reports of a partly-clothed man who was running violently in and out of four houses in Warrior Close, Portslade, and three in adjacent Brackenbury Close.

Officers tracked down the man in nearby Fox Way. He was holding a knife which he had picked up from one of the houses and confronted the officers.

He was tasered and arrested.

The 30-year-old man was taken to the Royal Sussex County Hospital in Brighton to be treated for what is believed to be an underlying health condition.

Police are currently waiting to interview him and are working to establish the motive his behaviour.

A woman at one of the address received injuries when her door was pushed open as the man ran past, and two police officers were slightly hurt as they restrained the man.

Chief Inspector Rachel Swinney said: "This was a frightening experience for the residents involved, even though none of them reported being directly threatened. With their help we resolved this incident very quickly.

"We have had thanks from local people for our response, and have reassured them that this was an isolated and swiftly contained event and there is no ongoing concern for their safety."
