The Red Line subway stop at Universal has reopened after being shut down about 4:38 a.m. while the Los Angeles Police Department investigated a possible pipe bomb in a vehicle near one of the station’s elevators, according to Metro officials. The station reopened before 7 a.m.

The LAPD apparently believed there may have been a bomb inside a vehicle they had stopped near the station, according to City News Service. There were also lane closures on the Hollywood Freeway due to the incident. Trains began bypassing the station due to the investigation and a bus bridge was operated between the North Hollywood and Highland stops.

It remains unclear if the device was actually a bomb. The L.A. Times is reporting that police plan to detonate or destroy it.
