Police are appealing for witnesses to come forward following two street robberies in Chorley town centre last Tuesday.
Both attacks were reported within four minutes of each other in almost identical circumstances.
The offender approached both his victims after they have used cash machines and threatened them with violence before stealing their property.
The first robbery took place around 6.30pm.
A 44-year-man was approached by a suspect holding a craft-knife in Lennon Street at the bottom of the West Street car park. He was punched in the face after said he did not have any cash.
A few minutes later on Market Street at Lloyds TBS bank the offender demanded cash from the victim, 47, and threatened to stab her before stealing her purse from her hand.
No knife was seen and the man then fled along St Mary’s Gate towards Devonshire Road. The offender is described as between 5ft 6ft tall, aged 18-30 years old and was wearing a dark coloured hooded tracksuit and white trainers.
His face may have been covered by a scarf. Officers attended the scene and made an immediate search of the area but the offender escaped.
A full investigation is now underway. DC Danielle Prendergast from Chorley CID said: “These robberies occurred in a busy town centre. I would urge anybody that thinks they saw a man matching the offenders’ description to contact police.
“Fortunately neither victim was hurt during the robberies but they are understandably shaken. We need the public’s help to catch the person responsible.”
Anyone with any information should contact police on 08451 253545 or Crimestoppers anonymously on 0800 555 111.
