Police are appealing for witnesses following an armed raid at an Illingworth chemist shop.
A man armed with a knife demanded drugs at Med Express, Turner Avenue South at 4.30 pm yesterday (Fri).
Detective Insp Craig Lord said the shop assistant was left distressed and frightened but unharmed.
The suspect is in his 20s, wore a light Polo shirt, black bottoms, a dark baseball cap and spoke with a possible Scottish accent.
He made off on foot and officers believe he might be local.
“We think somebody in the Illingworth area will know who this man is,” said Det Insp Lord.
Anyone with information should contact Calderdale CID on 101 or Crimestoppers anonymously on 0800 555 111
