RAIDERS escaped with thousands of pounds after clubbing a bar manager to the ground.
The two robbers went into the Ainley Top Brewers Fayre pub at about 11.30pm on Sunday as the bar manager had finished counting the night's takings.
As he returned to the cash office from the restaurant, he was struck with a hard object on the side of the head by the thieves.
He was alone downstairs when the intruders struck. Other staff were upstairs.
The raiders forced him to open the safe then they grabbed three bags containing about £8,500.
Acting Det Insp Andrew Garnett, of Calderdale CID, said: "The victim had a suspected fractured cheekbone and had to go back to hospital yesterday morning for further treatment.
"He was certainly very frightened by his ordeal.
"We think the robbers had slipped into the pub under cover of darkness."
The thieves are thought to have escaped by car.
Det Insp Garnett added: "Did anyone see a car being driven quickly away from the pub afterwards? If they did, which way did it go and do they have a description of it?"
Both robbers were described as Asian men. One was aged 25 to 30, 5ft 10in tall, with short black hair and a goatee beard. He spoke with a local accent and wore a black bomber jacket and black gloves.
His accomplice was just over 6ft and slim. He wore a white or cream baseball cap.
Anyone who saw anything suspicious or has any information about the robbery should contact Det Sgt Sean Kenyon at Calderdale CID on 01422 337059 or Crimestoppers anonymously on 0800 555 111.
