A man is his 50s is receiving hospital treatment after police were called to a house on the outskirts of Norwich.
Officers were called to Rosalie Close in Hellesdon at about 12.20pm after a neighbour raised concerns about a man in distress.
The man was aggressive towards officers and was seen to be holding a kitchen knife, resulting in armed units attending the scene.
Police had to force their way in and the man was tasered and restrained, allowing paramedics to treat him. He was detained and taken to hospital for treatment.
Police in Norwich say they are becoming increasingly concerned for the welfare of a missing 30-year-old man.
Jamie Kingshott, who is from King’s Lynn, absconded from Hellesdon Hospital in the city shortly before 2pm on Saturday 1 March.
He is described as white, 5ft 11, of slim build with light brown hair and bushy eyebrows, and was last seen wearing light blue jeans, a white t-shirt, dark blue Adidas trainers and a black rain jacket which has a burgundy patch on the back.
Anyone who has seen Mr Kingshott or knows of his whereabouts should contact Norfolk Police on 101.
A hospital in Norfolk which cares for people with mental health issues, has found to be failing in two key areas.
An inspection of Hellesdon Hospital was carried out by the Care Quality Commission in January.
It found the hospital was sometimes failing to respect patients' privacy, dignity and independence.
There were also concerns over waiting times for people to be assessed. The hospital said steps have already been taken to improve the situation
Police in Norfolk say an allegation has been made about the care a patient received at a Norwich hospital before he died.
A man in his late 40s, who had been receiving treatment at Hellesdon Hospital, had a medical emergency on Tuesday 1 October.
He was taken to the Norfolk and Norwich University Hospital, where he died three days later.
Detective Chief Inspector Tracey Little said the allegation related to "the care the patient received prior to and during the medical emergency" at Hellesdon Hospital.
"A Home Office post-mortem examination has been carried out but proved inconclusive and further tests will now be carried out," she added.
The death is being treated as unexplained.
Police said the investigation was not linked to "any other enquiries being undertaken by the Major Investigation Team".
