A 24-year-old man has been charged with manslaughter and failing to provide assistance over a crash that killed 15-year-old Aubin Grove boy, Mitchell Chase.
Mitchell died on December 29, less than 24 hours after the dirt bike he was riding collided with a Mitsubishi ASX being driver by a 49-year-old man at the intersection of Cotswold Parade and Giverny Gardens in Aubin Grove at 7.30pm.

But a separate driver, whose role in the crash has not been made clear, was charged on Thursday in relation to the teen's death.
Police had been publicly searching for his car, a black coloured Mercedes Benz, seizing it two days after the crash.

"After extensive inquiries by investigators, a 24-year-old man from Atwell was arrested on Thursday."
The accused man has been charged with manslaughter, failing to report an incident occasioning death, failing to stop and provide assistance and no authority to drive.
