CCTV has been released in the hunt for a penknife-armed would-be robber who held up a Bournemouth store.

The man, whose face was covered with a black scarf, entered the One Stop Community Store in Anchor Road at around 10.22pm and demanded cash from the till while waving the knife.

Dorset Police said that the two members of staff refused to hand over the cash and the man left the store empty handed. He ran off with a second man who had been waiting outside.

No arrests have been made and the force has issued an appeal for witnesses to come forward along with some CCTV images.

Detective Constable Angela Singleton, of Bournemouth CID, said: "This was a frightening incident for staff at the store.

"As part of my investigation I am now in a position to issue a CCTV image of the suspect. I appreciate that his face is covered but I am appealing to anyone who recognises the man from the clothing he is wearing to please call me urgently on 101.

"I would also like to hear from anyone who saw either man before or after the relevant time in the area of the One Stop store."

The suspect is described as white, five feet six inches tall, of big build and with light brown hair and a local accent.

He was wearing a grey hooded top with the hood up, matching grey jogging bottoms with white stripes down the side, black trainers with white soles and he had a black scarf covering his face.

Detectives believe he could be aged in his 20s from the way the witnesses reported his speech and mannerisms. He carried a drawstring JD sports bag.

The second man is described as shorter, of slim build, and was wearing a blue hooded top with the hood up, grey jogging bottoms and black trainers.

Witnesses and anyone with information should call Dorset Police in confidence on 101 quoting incident number 19:416. Alternatively, call the free and anonymous Crimestoppers line on 0800 555 111 where mobile phone tariffs may apply.
