Police have arrested two men following a robbery in which a shop assistant was threatened with a knife.

One man is still being sought by officers in connection with the incident, which took place on Wednesday.

A spokesperson for the police said: "After yesterday’s appeal following a robbery at Pam’s Pantry, we have made two arrests.

"But we do still want to speak to a third male (pictured) in connection with the incident."

The attempted robbery took place at Pam’s Pantry in Brierfield on March 25 and on Thursday police issued pictures of the suspects.

Around 2.15pm three men entered the Burnley Road shop, one carrying a knife, and threatened the shop assistant while another demanded money from the till.

After a struggle, all three left empty-handed and escaped towards Lord Street. There were no reported injuries.

The man police still want to speak with is white, of slim build, was wearing a black cap, a green jacket, grey tracksuit bottoms and black shoes.

Detective Constable Heather McAtee said: “This is a serious offence regardless of the current situation with COVID-19.

"However, I would like to stress that Pam’s Pantry is a local convenience shop selling essential supplies to the local community and this offence against the staff there who are key workers is totally unacceptable.

“If you recognise these men or have any idea of their whereabouts please get in touch. I would also appeal to members of the community who were in the area at the time and saw anything they now feel they need to report to please make contact.”

If you recognise these people please call 07967 823720 or email 4173@lancashire.pnn.police.uk .

If there is no response please contact 101 quoting log number 0691 of March 25.
