Pittsburgh Police from Zone 5 responded to a call for a hostile and armed male in the 600 block of Collins Street just after 10 p.m. 

When responding officers arrived on scene they were met by a male who threatened them before barricading himself inside an apartment building, refusing to come out. SWAT was called in, as the priority was to protect the other residents who were now considered hostages. EMS and Fire were also on scene.

SWAT operators were able to evacuate the hostages from the building and take them to a safe place. 

Police were unable to establish contact with the male actor still inside to negotiate with him, so multiple verbal hails were made to convince him to exit the residence. Those attempts were unsuccessful.

Eventually, gas munitions were deployed and, after some time, the male surrendered without further incident.

He was taken into custody and cleared medically by EMS before being transported to Allegheny County Jail.
