An armed robber threatened a man in an Oswaldtwistle alleyway before making off with cash.
The robber, who police believe may have been carrying a knife, struck at around 11.30am on Friday, January 11 in the rear alleyway of Roe Greave.
Detectives said the 23-year-old victim was approached by the offender who demanded he hand over his mobile phone.
DS Julie Cross Accrington Reactive CID said the victim didn’t have a phone on him so gave him money because he felt threatened.
The offender grabbed the cash and ran back down the alleyway towards Union Road.
DS Cross added: “Fortunately the victim was not hurt but we believe the offender was carrying some form of weapon, possibly a knife. I would appeal to anybody that saw a man acting suspiciously in the area around the time of the offence or with any information about this offence to call Lancashire Police on 101.”
The offender is described as being black, aged 16 to 19 years old, 5ft 9" tall, skinny build with a gaunt face.
He was wearing a black hat and black clothing.
