An "all clear" was announced after a bomb threat at a library on the campus of Texas A&M University was determined to be a hoax, school officials said Monday.

Bomb sniffing dogs, explosives experts and police had scoured the Evans Library and surrounding buildings for several hours Monday after a bomb threat, made by electronic communication, came in around 11:00am local time.

Surrounding buildings, including the Evans Library Annex, Cushing Library and the Student Computing Center were also evacuated as a "precautionary measure" according to the university's website.

Shortly before 3:00pm local time, school officials announced an end to the alert after "it was determined that the bomb threat reported this morning was a hoax." All facilities would remain closed until further notice, they said.
