Just before 1:45 a.m. Pittsburgh Police officers from Zone 3 responded to the 400 block of Alice Street for a domestic incident where shots were fired.

A female and a male resident were safely outside of the home when police arrived. There were no injuries.

SWAT and EMS tactical units were called in as the male suspect was believed to be barricaded inside, possibly with a handgun. Police also recovered a weapon from his vehicle.

SWAT operators conducted verbal hails while negotiators tried to establish contact with the male over the phone, but were unsuccessful. A K9 unit entered the residence after gas deployment failed to draw the suspect out of the home.

After a sweep of the residence, the suspect was not located inside.

The investigation is ongoing.
