A driver who was detained by police was almost four times over the drink drive limit, police say - despite being with their four-year-old child.

Norfolk and Suffolk Roads Policing tweeted just before midnight on Christmas Day to say a driver had been stopped on the A47 at King's Lynn earlier on Monday.

It came after reports from another motorist, and after police pulled the driver - who was travelling with their four-year-old child - over, a breath test for alcohol came back positive.

While in custody, another test gave a result of 135mg per 100 millilitres of breath. The legal limit is 35mg.
