Federal investigators have served warrants in California in connection with the investigation of the December attack that killed 14 people in San Bernardino.
FBI spokeswoman Laura Eimiller says the warrants were served early Thursday in the southern California cities of Corona and Ontario. She said the actions are linked to the San Bernardino shooting, but declined to share more details.
Reuters reported the Corona warrant was served at the home of Syed Raheel Farook, the brother of Syed Rizwan Farook the man who along with his wife, Tashfeen Malik opened fire at a December holiday party.
Farook was a county restaurant inspector and the people he shot were his co-workers at the San Bernardino County Health Department. He and his wife later died in a shootout with police.
