HOUSTON - A college in the US state of Texas issued a Code Maroon alert and closed a stadium and adjacent facilities on Wednesday after receiving a bomb threat.

Texas A&M University at College Station, Texas, said on its website Wednesday that university authorities were notified about 10:50 a.m. that a threat was "written on a wall of a non-academic facility on campus. "

"An investigation was launched immediately, and a Code Maroon emergency message was subsequently issued," the university said.

Approximately 700 people were evacuated from Kyle Field, Reed Building, G. Rollie White, Neetum Steed, and the Bright Athletics complex, and those evacuated buildings will "remain closed the rest of the day," it said.

Texas A&M authorities continue to investigate the incident, and federal agencies have been contacted to aid in the on-going investigation, the school said.

Code Maroon is the university's emergency notification system, which uses multiple methods of contacting students, faculty and the community.
