Raiders smashed their way into a bar before escaping with cash and a till.
The incident happened at the Three Wise Monkeys in Todmorden between 2.40am and 3.10am on Wednesday.
CCTV footage shows the three men forcing their way in to the building on Water Street and setting off the alarm. They then return half an hour later to remove the till, which contained over £100.
Business owner Matthanee Nilavongse said: “It feels like these people think they can do it and get away with it. We run a business and have an alarm to try to protect ourselves. But these people really don’t care.”
She thanked the public for their support, especially those who helped her clean up the following day. As well taking the cash, the raiders stole the £300 till and caused £150 worth of damage to the door.
PC Kathrine Wadsworth, of Calderdale Neighbourhood Investigation Unit (CNIU), said: “We are investigating a burglary at a business in Water Street, Todmorden, on Wednesday, 27 August. Between 2.40am and 3.10am, entry has been forced to the premise and a till and cash inside stolen.”
Witnesses are asked to call the CNIU on 101.
