DETECTIVES investigating a knifepoint robbery in Carlisle city centre have made two arrests.

They have also issued a photo of the bicycle used by the robber following the raid at St Nicholas Galleries, in Bank Street, at 3.40pm on Friday.

Officers are appealing for anyone who recognises the bike or knows who used it to come forward and get in touch.

The men who were arrested, both aged 42 and from Carlisle, have been released under investigation. One was arrested on suspicion of robbery the other on suspicion of conspiracy to commit robbery.

But police say the inquiry is ongoing and are continuing to appeal for witnesses and asking anyone who knows anything to contact officers.

Detective Inspector James Yallop is leading the investigation.

He said: “Two men have been arrested and released under investigation as part of the inquiry - but the investigation is continuing and we still need the public’s help.

“Please look carefully at the bike, it has distinctive features; look at the white brake cables, the rear mud guard and front suspension.

“If you recognise this bike and know the person who used it, please do the right thing and tell us.

“This is an important line of enquiry and the public can help solve this investigation.”

The suspect arrived at the shop on the bike, which was seized by police.

During the crime, he produced a knife before making off with jewellery on foot.

He is described as being about 5ft 9ins tall and of skinny build. He was wearing a dark grey jacket, light grey tracksuit bottoms and black trainers. It is believed he may have been wearing dark or black make-up to disguise his face.

Staff members from the shop were not injured and received support from officers.

If you know anything about the bike, or have any other information, call police on 101, quoting log 166 of March 22 – or call Crimestoppers, anonymously, on 0800 555 111.
