One student at Texas Southern University has been fatally shot and another man is in critical condition in an incident that left the school on lockdown for hours earlier today.

University spokeswoman Evan Pickens said that the injured victim has not been confirmed as a student at the university, and neither person who was shot has been named publicly.

Two male suspects have been detained, though Pickens did not know if they were students at the school.

The whole school was on lockdown for more than three hours following the shooting this morning, but the measure has since been lifted with the exception of the area immediately near the apartment complex, which is where the shooting reportedly took place.
