Concert Arrests: Forty people were arrested at a concert by the heavy metal rock group AC/DC at the Irvine Meadows Ampitheatre on Wednesday night, mostly for various drug and alcohol violations, a police spokesman said. Lt. Mike White said the 18 police officers assigned to the rock concert made all the arrests at the site. He said one theft from a vehicle and a mugging also were reported but that most of the arrests were made for drinking. “We had a few drunk-driving arrests also,” White said.
