GRAND RAPIDS, Mich. -- A Benton Harbor pharmacist who stopped an attempted armed robbery by firing his own handgun is suing Walgreens after the company fired him.

The robbery happened at 4:30 a.m. on May 8 at a Walgreens in Benton Harbor, Mich. 

In the video, you can see the robbers carrying guns when they entered the store.  A pharmacist, 36-year-old Jeremy Hoven, reacted and pulled his own gun to defend himself.  Hoven fired a few shots from behind the pharmacy counter and sent the robbers running.

A week later, Hoven was fired.  He says he had a permit to carry a concealed weapon.  Apparently, he did not notify his employer he was carrying a gun.

In August, Hoven filed a lawsuit in the U.S. District Court in Grand Rapids, Mich., claiming wrongful termination.  His attorneys released the surveillance video on Wednesday.

Walgreens is denying many of Hoven's claims, including that he was terminated over a "non-escalation" policy.
