Spokane police and SWAT responded to a home at Heroy and A Street, where there were possible shots fired.
A man at the home barricaded himself inside with a gun after police arrived. Police say the disturbance apparently began as a domestic dispute.
The man and the woman both walked out of the home after SWAT arrived. The man was detained but was not arrested. Police believe he may have been suicidal.
Spokane police will continue to investigate what happened.
