Authorities say a confrontation with an intoxicated man at a southern Arizona theater caused moviegoers to flee a screening of "The Dark Knight Rises" the same day a gunman killed 12 people at a Colorado cinema.

Cochise County sheriff's officials say 27-year-old Michael William Borboa entered a Cinemark theater in Sierra Vista on Friday carrying a backpack. Witnesses say he appeared to be drunk and was acting strangely during a showing of the same movie that was on screen when the Colorado shooting occurred.

Someone confronted the man. According to the sheriff's office, that caused "mass hysteria," and about 50 people fled the theater.

The Arizona Daily Star reports off-duty Border Patrol agents tackled Borboa. Authorities say his backpack contained an empty alcohol container and a half-empty moonshine bottle.

The man was arrested on suspicion of disorderly conduct, and threatening and intimidating.
