UPDATE: Urine Bottle 'Hoax' Package Evacuates High School

UPDATED (6:39 p.m.)—A student was charged with multiple violations after allegedly placing a bottle of urine to act as a stink bomb in a hallway Tuesday at  morning.

The school was evacuated around 11 a.m. after police responded to a report of a suspicious package. The academic building was locked down, with students being taken to the auditorium building.

A 17-year-old boy confessed to the incident and said it was a prank for the final day of school, according to a news release from the Maryland State Fire Marshal's Office.

The package was deemed a "hoax" in a 12:45 p.m. automated call from Harford County Public Schools.

The call said, "At this time, the Havre de Grace police have deemed the building safe for students and staff to re-enter. All students have returned safely to their classrooms and instruction will continue as normal for the remainder of the day. Police have confirmed that the suspicious item was a hoax however safety is our number one priority and we will always err on the side of caution. Thank you for your patience and understanding as we safely worked through the situation today. The students should be commended for remaining calm and their excellent behavior throughout this situation." 

The 17-year-old boy was charged with representation of a destructive device, disturbing school operations, reckless endangerment and disorderly conduct, according to the fire marshal.

The statement from the fire marshal's office said the boy was transported to the Charles H. Hickey Jr. School by the Department of Juvenile Services. He will face a preliminary hearing Wednesday. If convicted of the charges, the boy faces up to 15 months and eight years in jail and/or fines totaling $18,000, according to the fire marshal's office.

Tuesday was the final day of school for students in Harford County Public Schools.
