NSW top cop's son admits drink driving

The son of NSW Police Commissioner Mick Fuller has pleaded guilty to drink driving while his P-plate licence was suspended.

Jacob James Fuller, 20, was charged after he blew 0.031 after pulling up short of a roadside random breath test site at Waterfall in the early hours of September 8.

While under the regular limit of 0.05, Fuller was meant to have zero blood alcohol as a P-plater.

NSW Police told AAP in a statement in September officers approached Fuller's vehicle after it pulled up short of the breath testing site. They discovered his provisional licence was suspended after the positive test.

Fuller pleaded guilty on Thursday in Sutherland Local Court to driving while on a suspended licence and a drink-driving charge related to having an alcohol concentration between 0.02 and 0.05.

He will be sentenced on November 7 at Sydney's Downing Centre Local Court.
