UH campus security said it responded to a report of a break-in about 12:35 p.m. at the office of the Hawaii English Language Program in a portable on the lower campus.

A juvenile male was seen in the portable and fled, campus security said.

He is described as younger than 15, 5 feet 6 inches tall, weighing 100 pounds, with black hair, brown eyes and a tanned complexion. Campus security said a person fitting this description has been reported at other campus locations where minor thefts have occurred.
