A 15-YEAR-OLD boy is in hospital with life-threatening injuries after being struck in the head with a metal pole in Melbourne’s southeast overnight.

A group of males arrived outside a Cranbourne North home at about 12.25am on Thursday and two boys, aged 15, went outside to confront them, police said.

During the confrontation, one of the boys was struck in the head with a metal pole before the group fled the scene.

The Frankston teenager suffered life-threatening head injuries and was taken to hospital in a critical condition.

Neighbours told the Herald Sun groups of young people often run through the streets from the nearby train station and “cause trouble”.

“We have so much trouble in this street it’s ridiculous,” Ms Stewart told the paper.

“They bang on the fences, they graffiti the fences and litter everywhere ... beer bottles — I’ve even found needles.
