A third teenager has been charged over the alleged abduction and armed robbery of a schoolboy in Melbourne's east last week.
A 14-year-old boy was walking home with three friends when he was allegedly confronted by a group in a Volkswagen Tiguan about 3.35pm last Monday.
He was allegedly forced into the car, which drove along Neerim Road before he fell out in unknown circumstances near the intersection of Grange Road and sustained significant injuries.
Police arrested a 14-year-old girl this morning in Langwarrin.
She has been charged with multiple offences including dangerous driving, armed robbery and theft of a motor vehicle.
The girl has been bailed to appear at a children's court at a later date.
Two boys, aged 14 and 15, have also been charged over the incident.
