THIS quad biker carrying out an anti-social manouvre couldn't have timed it worse.

He pulls out in front of another vehicle in Exmoor National Park, kicks up a storm of dust and accelerates off.

Only, he didn't get very far.

The vehicle behind was driven by an Avon and Somerset special constable, who pulled the biker over.

@ASPSpecials tweeted: "How to get stopped & reported for offences by @ASPWSomerset #SpecialConstables on patrol @ExmoorNP yesterday (Saturday).

"AntiSocial use of #QuadBikes on our #NationalPark will not be tolerated as well as the danger to road users."
