POLICE investigating a knifepoint robbery on a 16-year-old boy have arrested two teenagers.

An 18-year-old and a 17-year-old, both from Liverpool, are being questioned by detectives.

The suspect, both males, were arrested on suspicion of robbery earlier today, Wednesday.

The victim was walking along a path between Main Avenue and Edge Street, Grange Park when he was approached by hooded offenders on Monday afternoon.

They allegedly made threats before taking the boy's coat, bag, cash, phone and watch.

The crime happened in broad daylight at 1.45pm.

The victim was left uninjured but extremely shaken.

Detective Inspector Jackie Guinness said "We would like to repeat our appeal for a male witness who we believe walked past at the time of the incident on Monday and could have been approached by the offenders.

“If this male could make contact we would like to speak to him as a priority, as we believe he could greatly assist the investigation."
