DAYTON, Ohio -- A Dayton man reportedly becomes Montgomery County's first person to violate the concealed carry law after deputies said he took a gun into a court building.

Investigators said Douglas Lyons walked into the Common Pleas Courts building in downtown Dayton on Tuesday with the gun.

Law enforcement officials say permit owners need to be careful about where they carry concealed weapons. They said gun owners are aware of what the law is and that there will be no warnings, but arrests.

If convicted, Lyons faces six months to a year in jail.
