A man jailed for four years is amongst three people sentenced for a canal side robbery in Lancaster.
Nathan Holden, 21, was with two teenagers when the group targeted a man walking along the canal on the afternoon of April 30.
The trio asked the man for the time and when he got his £200 mobile phone out to respond it was taken from him.
He was then punched to the head, a £500 camera was stolen from him and he was threatened with a pair of scissors.
Appearing at Burnley Crown Court, Holden, of Delamere Avenue, Heysham, was jailed for four years for robbery.
A 17-year-old, who cannot be named for legal reasons, was given a two year youth rehabilitation order and a 15-year-old, who also cannot be named, was given a two-year youth rehabilitation order with two year supervision, a curfew for two months and a 91-day activity requirement.
Speaking after the sentencing, Detective Constable Sue Palmer, Lancaster CID, said: “This was a frightening encounter for the victim, who was attacked and threatened in order for the group to get their hands on his property.”
“As Holden now knows, the police and the courts will not tolerate this behaviour and offenders face going to jail for their violent actions.”
