A teenage couple were robbed by two knife-wielding muggers as they made their way to a favourite restaurant for a Saturday night date.
The victim, a 16-year-old boy from Rainford, was walking along Water Street with his girlfriend on their way to a nearby restaurant when they passed two youngsters.
As they walked past, one of the youths asked him for the time and, when the boy took his iPhone 5 out of his pocket to check, the offender stood up and pulled a pocket knife out and pointed it at him.
The incident happened shortly after 4pm on Saturday, August 10.
The suspects were dressed in grey and black tracksuits.
Witnesses should call St Helens CID on 0151 777 6843 or Crimestoppers.
