An 88-year-old man was being treated for an unknown medical problem at his home on the 1200 block of Dwight Way about 1:45 a.m.
As firefighters tended to him, he began resisting their efforts, and firefighters called police to the home, authorities said.
As police officers were on their way, the man began firing from a handgun, police said.
He was taken by paramedics to a hospital for a psychiatric evaluation. Police would not say if he could face arrest or charges in the case. Several guns from the home were removed for safety reasons, police said.
