There's a new terror threat in Los Angeles.
Federal officials say the unsubstantiated threat says an attack may be planned for Thursday against a shopping mall in the Los Angeles area.
LAPD has been informed as have the mayor and California's governor.
The threat does not mention a specific mall but indicates the supposed target could be near the federal building in West Los Angeles.
Police are increasing patrols and are asking mall operators to beef up their security. In the meantime, the threat is being investigated by a joint terrorism task force.
A spokeswoman for the mayor emphasizes the threat has not been
corroborated. She says people in Los Angeles should remain "vigilant and alert" but "go on with their daily lives."
