Police have dropped an investigation into whether Formula One champion Lewis Hamilton broke New Zealand law by filming himself with a mobile phone while riding a motorcycle.
Hamilton, while visiting New Zealand before travelling to the Australian Grand Prix, posted two videos on social media - both taken from close range - showing him riding a Harley Davidson on an Auckland motorway.
It has been illegal in New Zealand to use a mobile phone while driving a vehicle since 2009.
A police spokesman was quoted by the New Zealand Herald as saying there was not enough evidence to show he was holding the phone at the time.
Police said he could have had a hands-free device attached to the motorcycle, which is legal.
