The 43-year-old gunman suffered three non-fatal gunshot wounds to each arm and a leg as he confronted the autoworker in the lobby of Citizens Bank.

The suspect, whose name was not released, was rushed by firefighters to St. John Hospital & Medical Center. He was reported to be in serious condition, but the injuries do not appear to be life-threatening.

Mayor Jim Fouts said the gunman pointed his weapon at the 63-year-old, who was simply defending himself.

"It's his Second Amendment right," Fouts said.

"I'm glad to see that more people are carrying guns," witness Gary Guyette told Fox 2. "And the bad guys think twice before they do something bad - and take care of business."

It is unlikely the 63-year-old will face charges for the shooting, according to police.

This incident comes just several weeks after Detroit Police Chief James Craig called on the law-abiding people of his community to arm themselves.

In 2014, the Detroit police department issued more than 1,100 handgun permits, while more than 8,100 guns were registered in the city.

The number of shootings and robberies dropped from 2013. Home invasions are down 17 percent so far this year, Craig said, following a drop of 38 percent last year.

Craig noted that in a survey of 1,800 felons, the respondents pointed to "armed citizens" as the thing they were most afraid of.
