Teenage Australian tennis star Bernard Tomic was reportedly locked in a stand-off with police at his Gold Coast home on Thursday after refusing to pull over in his high-powered sports car. Tomic, 19, has been granted a special exemption from his provisional licence to drive his bright orange Aus$150,000 (US$130,000) BMW M3 to and from tennis training, and shut himself in his house after police tried to pull him over. A police car followed him home with siren blazing after he failed to stop, and officers were waiting outside his house for the teen to come out, the Courier Mail newspaper said. World number 38 Tomic has previously accused police of targeting him when he is out in the high-octane vehicle. Gold Coast police said they were still working to confirm the report when contacted by AFP. Tomic fell to childhood idol Roger Federer in the battle for an Australian Open quarter-final berth last weekend.
