A police negotiator was sent to a city home after officers became concerned for the safety of a man.

During the incident in William Mear Gardens in Norwich's NR1 area, off Pilling Park Road, a man in his 40s was arrested on suspicion of harassment and possession of class B drugs.

He was taken to Aylsham police station for questioning, where he remains.

It happened at 6.39pm last night, when eyewitnesses reported seeing seven police cars parked on the road.

Emergency services, including fire, ambulance and a police support unit were also on scene.

Fire crews from Sprowston and Carrow were called to the incident at about 6.55pm, where they assisted police, and left shortly after 9pm.

Neighbours expressed concern over the incident.

Tony, who preferred not to give his surname, said it appeared police were negotiating with the man at a block of flats in the cul de sac.

“It is concerning for all other residents when there is so much police activity, though it is not the first time.

“It looked like a major incident with several police cars, fire engines and paramedics all here, but it was something that had escalated.”

Another neighbour added: “We get regular incidents around here. No one likes to see loads of police swarming on the road but they have a difficult job dealing with some people.”
