Armed man arrested at Phoenix Comicon; security to increase

Police are adding extra security at the Phoenix Comicon following the arrest of a man armed with guns and ammunition who allegedly posted online threats against officers.

"The threats indicated that he was armed and intended to kill police officers," said Sgt. Mercedes Fortune, a police spokeswoman.

The man was in possession of three handguns, a shotgun, a knife, ammunition, and a variety of other hand-held weapons along with wearing body armor, Fortune said.

He was taken into custody Thursday without incident after a brief struggle with police at the Phoenix Convention Center.

"He was immediately removed from the venue and taken to police headquarters for questioning," Fortune said. "At this time, there is no evidence to cause investigators to believe this is anything more than an isolated incident and not part of a grander scheme."

Officers working at the venue were alerted about noon to a suspicious man making threats against police on social media and the postings included photos of officers working the event, Fortune said.

The entertainment and comic convention began Thursday in the downtown area.

Prop weapons carried into the four-day event are supposed to be inspected by security staff, but police say the man's weapons weren't checked.

Police said extra security is being added with additional screening and fewer accessible entrances to the building.

"As an added precaution, weapons of any kinds — including simulated, replica or toy weapons — will not be permitted into the venue," Fortune added.
