Police responded to a bomb menace at a UCLA recreation middle Wednesday night time and college officers evacuated a number of residence halls on the Westwood campus.

A UCLA Bruin Alert — the campus emergency notification system — was issued about 12:20 a.m. Thursday, saying that the menace was unfounded and college students might return to their dorms.

The primary emergency alert was issued shortly after 10 p.m., telling the college group concerning the bomb menace at Sundown Canyon Recreation Middle.
