Police in St. John's say tips led to arrests of two drunk drivers overnight.

They say city workers and security guards at the Avalon Mall called shortly after 8:30 p.m. to report what is believed to be the same driver.

The Royal Newfoundland Constabulary said a 23-year-old was charged with impaired driving after they identified his vehicle in the mall’s parking lot.

A couple of hours later someone reported a possibly impaired driver in the Kilbride area of city.

The witness helped police locate a 45-year-old man who was charged with impaired driving.
