The man allegedly responsible for six hoax calls that sent SWAT teams into non-emergency situations has been arrested and released on bail Friday. Matthew Tollis, who was behind these so-called "swatting" prank calls according to police, was released on $100,000 bail after appearing in federal court.

Tollis, 21, from Wethersfield, Connecticut, is accused of calling in fake emergencies to authorities that sent heavily armed officers to a school or home. If he is convicted, he could face up to 15 years in prison.

Police arrested Tollis on Sept. 3 for his involvement in the April 3 swatting call that said there was a bomb found at the University of Connecticut. He is charged with three counts related to the UConn case along with three counts of federal conspiracy and aiding and abetting.

According to authorities, Tollis is part of an international group of "swatters" that go by the name TeAM Crucifix or Die. The pranks are done by disguising their phone numbers and calling 911, which sends the SWAT team. Often times, X-Box gamers who hijack people's social media accounts will refuse to release them until the victims make one of these prank calls.

An affidavit from federal court said that the group made false threats of attack, besides on UConn, on a home in Connecticut and multiple schools across the U.S., one even telling police that a man with an assault rifle was headed to the newly reopened Sandy Hook Elementary School, the site of the 2012 massacre of staff and young students.

The FBI said that over 400 swatting calls are made each year, which cost thousands in taxpayers' dollars each. Officials are trying to find other members in the ring of "swatters."

Before Tollis was due in court Friday, his attorney Jeremy Weingast had no comment.
