Police are appealing for information after up to three men forced their way into the Burnley home of a man on Sunday night, attacking him and demanding money.
The burglary took place around 9-40pm when the men kicked in the front door of a terraced property in Queen Victoria Road and rushed upstairs, claiming to be police.
The offenders forced their way into the back bedroom and demanded money from their 44-year-old victim him while hitting him with a crow bar.
When no money was handed over, the offenders ran from the scene empty handed towards Salus Street and then onto Wilton Street.
PC James Walton, from Burnley Police, said: “This is a serious offence in which an innocent man has been targeted in his own home, sustaining severe bruising and swelling to the arms and legs.
“The motive for this attack is unknown and I urge anyone with any information about those responsible to contact Lancashire Police on 101.
“We do not know at this stage if the men fled in a vehicle after the burglary but I’d be keen to hear from anyone who saw any vehicles leaving the area at speed.”
All three men are described as being of Asian heritage, aged in their 20s and around 5ft. 8in. tall.
The first man is said to be of a large build and was wearing western-style clothes, black gloves and a black balaclava. He spoke English.
The other men are described as being of proportionate build and were possibly wearing dark-coloured tracksuits.
