A vehicle was seized by police in Carrick at the weekend.
Officers are investigating a car theft and offences of driving without a licence or insurance.
Three motorists were arrested in the Carrick area for driving with excess alcohol.
The PSNI has warned that a number of vehicle checkpoints would be in operation after new legislation allows officers to carry out random breath tests. Previously, police needed a reasonable suspicion about the manner of someone’s driving, witnessed a traffic offence or called to a collision.
A PSNI spokesman warned that police will be conducting a number of pre-planned vehicle checkpoints.
