THESE security camera images show the moment when two masked robbers raided a shop in Dronfield armed with a knife and a hammer.
The robbery happened at Holmesdale Stores, on Holmesdale Road, and the shop assistant was left with cuts and bruises after being attacked by one of the crooks.
The men entered the shop at around 9.50pm on May 16, and one of the robbers approached the 28-year-old worker behind the counter and struck him with the hammer.
He demanded cash and a mobile phone, which was handed over before the robbers fled.
Police officers would like to speak to the men pictured in the CCTV images as part of their investigation.
DS Ryan Finnegan, from Derbyshire Police, said: “This was an appalling act of violence which has left the victim very shaken.”
Anyone who recognises the men or has any information should call 101 or Crimestoppers anonymously on 0800 555 111.
