David Kyem's Halloween costume sent Central Connecticut State University's campus into a frantic lockdown for three hours ending in his arrest, but now he has been arrested again, the Hartford Courant reported.

Kyem, 21, was ordered not to return to campus before meeting with the school's Office of Student Conduct. Kyem was originally arrested for breach of the peace and released on $1,000 bail. He was arrested Tuesday for first-degree criminal trespassing, according to a CCSU Police press release.

Kyem was informed in writing and verbally not to be on campus until after his meeting with school officials. His next court date was already scheduled for Nov. 14 for the original arrest and the second one will not change that, the release said.

The 21-year-old senior caused a campus-wide lockdown when he walked off a bus and onto campus wearing a mask, camouflage pants, a vest and carrying a fake sword and rifle. The getup was his Halloween costume he wore the previous weekend for a party while staying at the University of Connecticut. He said all the various costume pieces did not fit in his backpack, so he simply wore the full costume when his friend gave him a ride back to New Britain.

"I'm sorry for all the commotion and the fear and the confusion," Kyem said Monday night. "I'm sorry for any problems. It's obviously a big misunderstanding."

Police released Monday surveillance photos and other images of Kyem's costume. The image obtained from James Hall's surveillance camera shows Kyem wearing the mask and his hood pulled up over his head, revealing no part of his head. He also wore gloves, kneepads and combat boots, along with what one 911 called thought was a real sword and handgun.

CCSU police chief Chris Cervoni acknowledged all of Kyem's weaponry was fake, but added he has heard nothing but praise for the way law enforcement reacted to the alarm caused on campus.

Kyem was originally taken into custody with his two roommates, originally classified as "persons of interest," but it is not clear what legal action, if any, is being taken agains them.
