Police arrested a driver who gave a positive drug test an hour after smoking cannabis.

Officers pulled over a car at Tesco, in Thetford, last night. One tweeted: 'Vehicle pulled up outside Tesco Thetford earlier with a strong smell of cannabis coming from it.

'The driver admitted to smoking cannabis daily and just one hour beforehand. Provided positive sample on @DrugWipeUK #arrested #Fatal4 @BrecklandPolice #1787.'

Officers also pulled over a vehicle in Great Yarmouth for having a defective brake light last night and arrested the female driver after she tested positive for drugs.
