ATLANTA -- The Georgia Tech student accused of planting explosive water bottles on campus was released from jail Wednesday afternoon after posting bond.

Theodore Hollot, 18, said he had "tons" of regrets as he walked through a media throng following his release from the Fulton County Jail.

Hollot, scheduled to return to court on Oct. 19 for an arraignment hearing, is facing two charges, including felony possession of a destructive device and reckless conduct, a misdemeanor.

After a brief hearing, Judge Roy Roberts set bond at $7,000 for Hollot, and ordered the student to stay away from the Tech campus during his suspension from class. The bond had been initially set at $15,000 but was cut after a second hearing in which Hollot was represented by his own lawyer instead of a court-appointed lawyer.

Hollot posted a signature bond and was immediately released from confinement.

The student, a nuclear and radiological engineering major from Pennsylvania, surrendered to Georgia Tech police Tuesday morning and was suspended from school pending the investigation, Georgia Tech Assistant Vice President Amelia Gambino told reporters during a news conference.

A friend praised Hollot's decision to admit his involvement.

"I thought it was a very stand-up thing to confess," said Derek Deraps, who lives in the same dorm with Hollot. "I was proud of him for fessing up," Deraps said.

The incident prompted a terrorism investigation and the early-morning evacuation of students from two residential dorms.

No injuries were reported from the incident, although the janitor who found the devices was taken to a local medical clinic for evaluation.

Authorities were called to the Tech campus in northwest Atlanta shortly after 9 a.m. Monday after receiving a report of an explosive device that was detonated in a building in the 100 block of Bobby Dodd Way.

About 100 students were evacuated from Cloudman and Glenn residence halls while police investigated the devices.

Police said two soda bottles fashioned to look like bombs were found in the courtyard of one of the buildings. A janitor found one of the devices and it exploded in his hands as he picked it up.

Authorities said it appears that the incident was a prank and not an act of terrorism, which had been investigated as police looked for clues.
