An appeal has been launched after men armed with a knife and a hammer raided a convenience shop in Lancashire, say police.
Police were called to reports of the armed robbery shortly before 11pm on Wednesday April 25, after two men went into One Stop Shop in Pritchard Street, Blackburn.
Detectives say two men entered the shop armed with a hammer and a knife while another waited outside the door.
The men in the shop are reported to have demanded money from the till but a member of staff pressed the panic button and the pair fled empty handed.
Det Sgt Mark Holland, of Lancashire Constabulary’s East Division CID, said: “The men had their hoods up and their faces covered but we would like to speak to anyone who recognises them from their clothing in the CCTV footage.
“We’d also like to speak to anyone who saw anyone acting suspiciously in the area around the time of the robbery.
“We know two men went into the shop and another waited outside but it is possible there were more people involved.”
One man was wearing a khaki tracksuit and a balaclava, the other was dressed in a black puffa jacket and trousers.
The man outside was wearing a long black jacket and dark coloured clothing.
