UPDATE: Police have traced the female witness in relation to the robbery but are still appealing for information on the offender.
ORIGINAL STORY: Two people are being sought by police following a robbery at a Spalding Building Society on October 24.
Just before 5pm, a man entered the Norwich and Peterborough branch in Sheep Market and demanded money. No weapon was seen or mentioned but the suspect had one of his hands concealed.
He left the branch with an undisclosed amount of cash. Staff were shaken by the incident but nobody was injured.
He is described as average build, around 6ft 2ins tall, with light blonde hair. He had an English accent and was wearing jeans, a baseball cap, dark jacket and had a scarf around his face.
Police would also like to trace a woman who was in the branch asking to change Euros immediately before the incident and who may be an important witness.
