'A Miami Beach man is in custody after he caused a panic in a theater during a showing of "The Dark Knight Rises," police said Tuesday. According to a Miami Beach Police arrest affidavit, 44-year-old David Martin Escamillo was at the Regal Movie Theater late Monday night when he got into an altercation with another moviegoer, left the theater and returned wearing black gloves and screamed "This is it!" from the back of the theater. Escamillo's actions sent a hundred moviegoers fleeing for the exits, the affidavit said. When officers responded to the theater to a call of shots fired, they found three moviegoers detaining Escamillo, who was screaming, "I didn't shoot anybody," the affidavit said. James Butler said he and his brother were two of them. They waited outside the theater and chased Escamillo down and held him until police arrived. "My instincts kicked in, and I was like, let's get this guy. He was screaming, 'I never shot anyone, I never hurt anyone,'" Butler said. Escamillo, who sounded irrational and had a strong smell of alcohol on his breath, was taken into custody, the affidavit noted." - NBC News
