(Reuters) - A bomb threat at Texas Southern University, one of the largest historically black universities in the United States, triggered an evacuation of the campus on Wednesday, but students were allowed back after a sweep, officials said.
The threat to the school in Houston was made in a call to emergency dispatchers, Houston police spokeswoman Jodi Silva said by phone.
"It was a generalized bomb threat," Silva said.
Thousands of students, including those in dorms, were forced to leave the campus and classes were canceled for Wednesday, Steve Scheffler, a spokesman for the university, said by phone.
Police conducted a sweep of the campus and the school was declared safe, with students allowed to return, Scheffler said.
Classes at the school, which was founded in 1927, will resume on Thursday, he said.
Student Jaylan Jones told Houston television station KTRK that he was at a meeting when a university official took a phone call and came back to tell people to evacuate because of a bomb threat.
"I was extremely nervous. I didn't feel comfortable or safe," Jones told the station.
Students gathered on the street in front of the campus, according to local media.
