Schools in Florida's second-largest county are on lock down as a precaution after police say a woman called a radio station and said her husband was going to a school to start shooting.
Broward County schools were locked down Wednesday after the woman told the radio station her husband was going to start shooting at a school in Pembroke Pines, a Fort Lauderdale suburb.
Police say there is no credible threat and that all schools are safe.
Police say an e-mail was also sent to the radio station, saying "something big was going to happen," possibly at a post office or at a school.
Investigators have not confirmed the identity of the man or woman.
