The Dallas Police Department is investigating after officers said an armed man locked himself inside a home Monday morning before setting it on fire.

Officers said they responded around 6 a.m. to an armed disturbance call along the 600 block of Delaware Avenue. The department said they determined a man with a weapon had threatened a woman and child before barricading himself inside the home. Police said the man then set the home on fire.

Police said the woman and child are safe. Crews from Dallas Fire-Rescue arrived around 7:30 a.m., but the department said they could not enter the home for safety reasons. They did, however, work to protect anything around the house, including other homes. 

DFR said the home in question was heavily damaged by the blaze.

Dallas Police said the investigation is still active and ongoing.
