A 20-year-old man was left terrified after four men threatened him with a knife.
The victim was walking from his home in Lostock Hall along the old tram road to Brownedge Road when he was confronted by four men dressed in black.
They initially engaged him in conversation but then demanded he hand over his property, saying that if he did not they would stab him.
They did not produce a knife but the victim was so scared he handed over an iPhone 4. The incident happened between 11pm and midnight on Tuesday.
