Mathew Sterling, 30, was wearing all black clothing, body armor and was heavily armed when he allegedly made threats towards police officers inside the Phoenix Convention Center during Phoenix Comicon on May 25.

Following Sterling's arrest, many security changes occurred, including the banning of prop weapons.

He's being held on $1 million cash bond and is scheduled to appear in court on July 25.
