All-clear issued following reports of armed person on TCU campus
A tweet from the school at 7:16 a.m. Central time advised those on campus to immediately seek shelter.
Students were told to shelter in place until an all-clear was given.
According to TCU 360, Fort Worth police said the alert was prompted by a road rage incident between two Roadrunner Shuttle drivers. One driver reportedly shot at another, who was not injured, before fleeing.
At 8:01 a.m., TCU tweeted that the lockdown remained in effect. Those on campus were advised to look for a black male wearing black pants and a white shirt, driving shuttle No. 24171.
Fort Worth police said at 8:47 a.m. a suspect was in custody.
During a press conference, police said the campus was placed on lockdown out of an "over-abundance" of caution and stressed that no one on campus was injured.
TCU said all classes beginning after noon would be held as scheduled.
Tuesday's incident comes less than 48 hours after a gunman killed 26 people and wounded about 20 others in a Sutherland Springs, Texas, Baptist church.
