Armed police were called to a Norwich road after a young man was stabbed in the back, leaving him in hospital with serious injuries.

A man in his 20s was taken to the Norfolk and Norwich University Hospital following the attack, which happened at an address in Gertrude Road, in the north of the city.

Armed officers were sent to the street following the attack and officers from Norfolk police tonight arrested a man in his 30s.

A Norfolk Constabulary spokesperson said: 'Police were called to an address on Gertrude Road in Norwich shortly before 5pm, following reports a man had been stabbed in the back.

'He is said to be in a stable condition.

'The suspect, a man in his 30s, has been detained and is awaiting questioning.'

Blue and white police tape prevented vehicles from getting any further than the junction with Violet Road on the Sprowston Road side of the street.

One man who lives in the area said: 'The police have been here since about 5pm.

'I saw them with their guns looking around in the gutters with lights, but I don't know what's happened.'

Another said: 'I was walking the dog and saw there were police cars and then there were four, five, six of them up here.'

At one point, there were at least five police cars in the street, with one of them blocking off traffic close to the Co-op store.

But that vehicle, and a number of other police cars left at about 7.30pm.

Police crime scene investigators arrived in a forensics van shortly afterwards.

Police were allowing people who live in the street to go past the blue tape.

But police officers were urging them to stick to one side of the road, away from the address where the stabbing happened.

Anyone who saw the stabbing, or has information in connection with it, should contact Norfolk police on 101 or call Crimestoppers anonymously on 0800 555 111.
