Charges have been upgraded against the teenage boy accused of driving a stolen car that hit and killed beloved Wollert motorcyclist Davide Pollina, 19.

The boy, 16, who remains on bail, was hit with a fresh charge of culpable driving causing death on Monday over the Preston crash in August.

The added charge – an increase from his current dangerous driving causing death offence – means the maximum possible jail term the boy could face has now doubled from 10 years to 20 years.

The teen is accused of driving the stolen BMW that hit motorcyclist Mr Pollina as he was heading to his girlfriend’s house on Sunday, August 11.

Two boys in the BMW allegedly fled the scene before they were later arrested and charged.

It’s understood the crash followed an earlier aggravated burglary allegedly committed by three schoolmates in Pascoe Vale.

The trio were accused of stealing two cars, with two boys getting into the BMW and a third boy driving off in a second vehicle.

Soon after, the duo was allegedly involved in the deadly smash before fleeing the scene.

The three boys, aged between 16 and 17, have all been charged and bailed and continue to attend school together.

Davide Pollina was heading to his girlfriend’s house when he was killed in the crash.

All three were called before a children’s court on Monday, where an additional charge was filed against the alleged driver, 16.

The boy attended court with his mother, where a magistrate was told he hadn’t breached bail, continued to turn up to school and that youth justice – initially not supportive of him getting supervised bail – was now on board.

“From what I’ve read in the report he’s done everything that’s required of him,” the magistrate said.

“That’s very pleasing to see there’s no reason to interfere with your bail and I intend to keep your bail going.”

He was ordered to return to court in December.

The two other boys had their cases adjourned to October.
