A school assignment landed a Summerville teen in hot water Tuesday, reportedly for writing that he "bought a gun to take care of business," according to police.

When questioned by school administrators, the 16-year-old Summerville High School student said his words were just a joke, an incident report stated.

The school's students were held in their classrooms while officers conducted a search of the teen's locker and bookbag. No weapon was ever found, according to Summerville police. Officers placed the "irate" student in handcuffs and detained him for disturbing schools, the report said.

He was later released into his mother's care, police said.
