The FBI says it is investigating an "imminent" terror threat against a Los Angeles Metro station located near Universal Studios in Hollywood.
The threat, which Los Angeles Mayor Eric Garcetti said was phoned in "from a nation abroad" and made against the city's Universal City Metro station on the red line, according to KABC-TV. The individual who phoned in the threat said the attack would occur Tuesday morning.
The FBI's assistant director at the Los Angeles field office, Deidre Fike, didn't say which country the call came from but said the individual who made the threat spoke in English, KTLA-TV reported.
Authorities said what made this threat so credible was the specificity with which it was made, and the timing given by whoever threatened it.
In the meantime, water-filled barriers, a bomb-sniffing dog and armed Los Angeles County sheriff's deputies were seen outside the Metro station, just steps from the popular tourist attraction. A representative for Universal Studios did not immediately return a request for comment from TheBlaze on Tuesday.
Los Angeles County Sheriff Jim McDonnell is urging the public to remain calm and vigilant as authorities continue the investigation.
This could be real, it could be a hoax," McDonnell said at a news conference Monday night.
