A DUI sweep and checkpoint produced big numbers for the Salt Lake police on Saturday.

Officers made 36 drunken driving arrests and impounded 76 cars during the sweep, detective Dave Warner said. Police also made four felony arrests for outstanding warrants and possession of drugs."It was the largest checkpoint we've conducted in recent years, and we were surprised it was so successful," Warner said.

Officers checked nearly 700 cars at 300 W. 750 South from 10 p.m. Friday to 2 a.m. Saturday. Volunteers from the department's community unit patrolled the area in cars, looking for intoxicated drivers.

"As amazing as it was, we got through it without a hitch," Warner said. "Nobody tried to flee or fight the police. The biggest problem was trying to find enough tow trucks."

Officers are planning another sweep in Salt Lake City sometime in the next month, he said.
