The FBI said late Tuesday that investigators found no evidence to verify that a bomb threat to L.A.'s subway system was credible.
The FBI's Joint Terrorism Task Force announced Monday evening a specific and imminent but uncorroborated threat in which an anonymous male in a foreign country called a public safety hotline and said that an "attacker would detonate something" at the Metro's Red Line Universal City Station Tuesday, FBI spokeswoman Laura Eimiller said.
