Police fatally shot an armed person at a summer sports camp just outside of Dallas on Monday, authorities said. No children were harmed during the incident.
Dispatchers began receiving 911 calls at 8:43 a.m. CDT that a person with a gun was inside the Duncanville Fieldhouse, where more than 150 children were attending camp, Duncanville police representative Michelle Arias told reporters.
Officers arrived in two minutes, entered the building and looked for that armed individual, according to Arias.
"Officers located a subject armed with a gun and engaged the subject," Arias said. "The subject was struck (by gunfire)."
Officers rendered medical assistance and that person was taken to a hospital and pronounced dead there, police said.
No children were injured and they were cleared from the building and being reunited with parents at the nearby Duncanville Recreation Center, authorities said.
