A 17-year-old boy accused of stealing a mobile phone from a schoolgirl was arrested after being hit by a car while fleeing three off-duty policemen in Tin Hau yesterday. The boy was in stable condition last night in Ruttonjee Hospital with injuries to his head and hand. The boy allegedly snatched the phone from the girl in Causeway Road about 7.45am and ran towards North Point. The girl shouted for help, alerting the off-duty officers. After running about 200 metres, the boy was hit by a Mercedes-Benz driven by a 45-year-old woman in King's Road.
