Officials at a Maryland university say 30 students on a trip to South Africa will return home early after they were robbed at gunpoint on a tour bus.
Four people with a gun stopped the students' bus in Pretoria, South Africa, and took cash and passports on Sunday, said officials at the Baltimore-area Stevenson University.
No one was injured during the robbery, which occurred on the second day of a five-week educational trip.
Humanities and Social Sciences Dean Jim Salvucci says officials are confident that students are safe, but they are being brought back to the United States as a precaution.
Former Baltimore police Commissioner Frederick Bealefeld, who is now a faculty member chaperoning the trip, says students "remained calm and focused despite the pressure and fear."
