The campus of Southern Methodist University and Stonewall Jackson Elementary School in Dallas were both briefly on lockdown Friday morning due to reports of an armed man in the area.
According to the Dallas Police Department, a man called police and said he wanted to harm himself.
Police said officers were dispatched to the 6000 block of Melody Lane and made entry into an apartment, but the caller had already left the residence. Inside, police found a suicide note that indicated he might be a danger to himself or others.

Meanwhile, as nearby school campuses went on lockdown as a precaution, SMU sent out alerts, including tweets, that there was an "active shooter" on campus near Airline and Dyer. Some students questioned the school's use of the language which prompted panic and tears for some.
At 9:10 a.m., police found the man on the 5400 block of East Mockingbird Lane and took him into custody without incident.
With the man in custody, lock downs at both campuses were lifted.
The only weapons on the man were two small pocketknives, police said, and there was no evidence to indicate he was a threat to anyone.
The man was transported to an area hospital for observation, police said.
