A motorist seen driving 'erratically' in west Norfolk was found to be over the drink-drive limit.

Police officers stopped a Porsche on the A10 at Downham Market on Sunday night after a member of the public called in about the erratic manner of its driving.

NS Police Dogs said on Twitter that the driver failed a breath test and was taken into custody.

They thanked officers from King's Lynn for "great teamwork" and the "eagle-eyed" member of the public who made the call.
