In his case they arrested him for reckless and negligent driving, they would have also possibly taken him for a blood test.
With this sort of arrest you are held until the next available court date which would have been Monday.
The officer would open a docket and then the detective and the prosecutor would decide whether to pursue it or not.
If you are arrested you cannot refuse, they will tell you that they are arresting you for, since it is and arrest there is no need for a warrant. If you refuse to come they can and will use all reasonable force to affect the arrest.
A broken Bouwer spoke openly to Rapport about his nightmare experience that began when he was arrested on January 6 because a police officer thought he had been driving recklessly.
It would be a very very bad idea to drive off especially after they have informed you that you are under arrest.
While I am deeply sorry for this gentleman, the police cannot be expected to baby-sit prisoners 24/7, He would have been place in a cell with other prisoners, possibly they had no empty cells to put him in by himself. The officer on duty should have made hourly checks.
If there was negligence then the office responsible should be punished and Mr Bouwer should be compensated
