An 83-year-old man was burgled after being confronted by a man on the doorstep of his Leyland home.
Police are appealing for information after the incident on Wellington Avenue at around 8pm on Tuesday, October 1.
The victim answered a knock on the door of his home and when he answered was confronted by a man armed a knife.
The thug pushed his way in and knocked the pensioner to the floor, before searching him and causing a cut to his hands.
The elderly man was then forced to hand over cash before the offender fled the scene.
Detective Sergeant Lee Anfield from Leyland CID said: “This is a horrific crime in which a vulnerable old man has been targeted in his own home.
“He was left very shaken by his ordeal and was taken to Royal Preston Hospital for treatment to cuts to his hands.
“He is being cared for by family and neighbours but it is vital this man is caught and we need the public’s help.
“I’d urge anybody that saw anything suspicious in the area of Wellington Avenue to contact us immediately.”
The offender is described as being a white man, aged in his late 30’s, 6ft tall and heavy build. He spoke with local accent and was wearing a balaclava.
Anyone with any information about this incident should contact Lancashire Police on 101.
