Baltimore County police arrested a 21-year-old Havre de Grace man on Friday in connection to the alleged assault of a male student in a school bathroom Thursday morning.

Sean Thomas Schleigh, of the 1100-block of Oaktree Dr. in Havre de Grace, has been charged with two counts of attempted second-degree sex offense, second-degree assault, false imprisonment, resisting arrest, and second-degree assault on the police officer.

He is being held in the Baltimore County Detention Center on $1 million dollars bail.

Baltimore County Police Lt. Rob McCullough told Patch.com yesterday after the incident that the attack occurred around 8:30 a.m. as students were arriving at school.

McCullough said that an adult male entered the school, and then followed a male juvenile student into a school bathroom, where he began attacking the student.

"He attempted to assault the  kid," McCullough said, adding that the attacker's motive was unclear.

 According to McCullough, the student did not suffer any significant injuries in the attack. McCollough said no other students were involved in the incident.

Schleigh, according to court records, was charged in October in Baltimore City District Court with theft of less than $100.

In 2009, Schleigh was charged with possession of marijuana in the District Court for Baltimore City and received a "nolle prosequi" disposition.

Previously, he pleaded guilty in 2008 to trespassing, a charge for which he received unsupervised probation before judgement, according to court records.

Several addresses have been listed in previous arrest records, including addresses in Baltimore City, West Virginia and South Carolina. He appears to have had family connections to Dundalk in the past and the eastern Baltimore County area, according to Internet records and Web pages.

A staff member heard the student screaming, McCullough said, and broke up the attack. A female school police officer responded and subdued the attacker after a brief struggle as he tried to escape.

Charles Herndon, communications director for the Baltimore County Public School system, said the intruder snuck into the school among students as the school was opening.

McCollough and Herndon said it is not believed at this time that the attacker, taken into custody at the North Point Precinct, had any connection to the school or any students.

Herdon said that attacker apparently mixed in with students as they entered the school at the start of the school day. Normally, the school's doors are locked and anyone entering the school has to be buzzed in by a school employee.

McCollough said the incident is the first of its kind this school year in Baltimore County.

"The security at Holabird is very good," Herndon said. "But we will be taking a look at our security here after this. Everyone responded to this as they should."

According WBAL, which first reported the incident Thursday, parents picking up their children early because of the snow were furious to hear about the incident.

"That could have been my son in the bathroom this morning, or my nephew who goes here. So, I'm very concerned about it," parent Cynthia Mohler told WBAL. Another concerned family member told 11 News that he found it disturbing that anyone who doesn't belong in the school can get by the school office unchallenged.

"You've got to see him walk through there. Every time I go to that school, they look right at me and say, 'Hey, you've got to go to the office.' And if he's past the office, someone should have said, 'Hey, what are you doing?'" parent Rob Dehn told WBAL.
