Around 6.10pm last night a man brandishing a knife demanded cash from staff at Fielding Court Newsagent’s.
He fled with notes and coins from the cash register. No-one was hurt.
A Northumbria Police spokesman said it is believed the man was loitering around the area of Fielding Court shops before the robbery took place.
He said: “The man brandished a knife at staff and demanded cash.
“He was 16-18-years-old, about 5ft8in to 5ft9in, thin, and at the time of the offence wore a black hooded coat, with black tracksuit bottoms, dark trainers, and a black scarf around the lower part of his face.”
