NT driver clocked at six times legal limit

A man has been caught driving at almost six times the blood-alcohol limit while banned for an almost identical offence in Darwin.

The 47-year-old was arrested after blowing .294 in Berrimah on Wednesday, police say.

He was driving without a licence after being nabbed at .284 last year.

Darwin Senior Sergeant Garry Smith took to social media with his disbelief and begged motorists not to drink-drive.

"Angry tears of frustration - what is the answer???" he wrote on Facebook on Thursday.

"Along with his two passengers, how many other lives did this chap put at risk?"
