A Pembroke Pines Middle School was evacuated Tuesday morning after police learned of a bomb threat.
Silver Trail Middle School was evacuated as a precaution after the "vague" threat was received by email overnight, police said.
School officials evacuated the school at Sheridan Street and Northwest 184th Avenue as a precaution until it could be searched by police dogs.
Officers searched the school and found nothing, and students were allowed to return to classes. The incident is being investigated.
