League City authorities last week arrested a teenager in relation to a fire in a bathroom at Clear Falls High School, the city said Monday.
A 15-year-old was arrested Thursday and charged with arson, according to the city.
The city did not release the name or other identifying information about the teenager.
The fire in a second-floor bathroom caused students and staff to evacuate Clear Falls High School on Jan. 30. The fire was extinguished by a staff member, but still caused an estimated $10,000 in damage to the bathroom and an adjacent hallway, officials said.
No one was injured in the fire.
