A customer at the Eastridge Movies 4 theater told police he threw a computer monitor through a glass door Tuesday evening after being refused a refund.

Police arrested David Anthony Vaughn, 55, at the Eastridge Mall on suspicion of property damage and disturbing the peace. Vaughn told the officer who arrested him that "he had done the right thing in the war against injustice in the world," according to a police affidavit.

Officers responded to the theater just after 7 p.m. and found Vaughn sweating profusely near the shoe department at JC Penney.

He told Sgt. Richie Randel that theater employees refused to give him his money back after the movie projector malfunctioned when he was watching "Iron Man," according to an affidavit signed by Randel. Instead, the employees offered him a voucher to see another movie.

According to witnesses, Vaughn became agitated as theater employees tried to explain their policy to him, yelling at workers and telling other patrons they were being ripped off. One customer heard him say that he was going to get his money's worth before he ripped a computer monitor from the ticket counter and threw it through the glass door.

After breaking the glass, the monitor came to rest by a table in the mall food court. Police found the computer upside down and underneath the ticket counter.

Vaughn told Randel his actions were justified because the theater refused to refund a patron's money, according to the affidavit. He was arrested and booked into Natrona County Detention Center, where he remained held Wednesday afternoon.

The damage from the incident was estimated at $1,250.
