Coronado High School students are getting back to work after a bomb threat was called in Monday morning.
Students were evacuated onto the football field during the search.
Law enforcement gave the all-clear around 10:40 a.m.
LISD released this statement Monday morning:
"About 9:45 a.m. this morning, Coronado High School received two prank calls claiming there was a bomb in the building. Out of an abundance of caution, the building was cleared. Law enforcement and administration did an extensive sweep of the school and found no evidence that this was anything other than a prank, and students were returned to the building. We are asking parents and students not to lend credence to this situation, since the perpetrator is clearly seeking attention. A thorough police investigation is underway. We will be taking aggressive action against the person responsible for this senseless hoax."
