Hamilton disregards questions about Harley selfies

Lewis Hamilton refused to entertain questions about the police investigation which has clouded the build-up to the defence of his Formula One crown.

The 31-year-old Briton faced a police probe after he posted a number of videos to his Snapchat account while riding a motorbike in New Zealand earlier this week.

Police in Auckland chose not to take any further action against the three-time world champion, citing a lack of ''sufficient evidence''. It has been illegal to use a mobile phone while driving a vehicle in New Zealand since 2009.

Asked if he felt he had a responsibility not to use his mobile phone whilst on a motorbike, Hamilton replied: "I don't really have much of an answer for you unfortunately."

Hamilton, who was using his phone throughout Thursday's press conference, was then asked if he felt he should set a better example.

"Once again I don't really have much of an answer for you," Hamilton, 31, said.
