LOS ANGELES _ Authorities are evacuating a postal facility in South Los Angeles after workers found a suspicious package addressed to Rep. Maxine Waters, D-Calif., law enforcement sources said.
The Los Angeles Police Department and federal Bureau of Alcohol, Tobacco, Firearms and Explosives are on the scene investigating the package.
Officials plan to deploy a robot to examine the package, the sources said.
The LAPD received a call about a suspicious package at 2 p.m. at the Los Angeles Central Mail facility on South Central Avenue, authorities said.
"We are working closely with our federal law enforcement partners given the number of suspicious devices discovered across the nation," the department said in a tweet.
Packages containing makeshift pipe bombs and addressed to high-profile political targets, including former President Barack Obama and former Secretary of State Hillary Clinton, set off a wave of panic Wednesday.
Waters also had a suspicious package destined for her Washington, D.C., office that was intercepted at a Maryland mail facility. Officials are unsure if that package is related to the other cases.
