Investigations after underway after staff at a Norwich shop were threatened during a knife point robbery.

Police were called to the One Stop shop on Woodcock Road, off Aylsham Road to the north of the city, just before 10pm on Tuesday night.

Officers said two men entered the shop, including one who was seen with a knife, and threatened members of staff, demanding money from the cash register.

They said the men did leave with some cash, though it is not yet clear how much.

On Wednesday morning, the shop remained closed and cordoned off with police tape.

A notice on the window said it was unlikely to reopen until at least 1pm on Wednesday.

Neighbouring businesses and those living near the shop said they did not hear anything during the incident, and only became aware of it after seeing the police tape on Wednesday morning.

One person, who lives across the road from the shop, said: 'We didn't hear anything in the night - we only realised what had happened when we went over to use the shop this morning and saw the tape.'

Members of staff at the store said they were not able to comment on what had happened.

According to police figures, there were 21 crimes reported on or near Woodcock Road in 2018.

Among them were five reports of violent or sexual offences, five of criminal damage and arson and five of anti-social behaviour.

Police have confirmed that Tuesday's incident is being treated as a robbery, and say they are now investigating what happened.

They asked anyone who witnessed anything or who may have information to come forward and get in touch in 101, quoting crime reference 36/16993/19.
