Officials plan to meet with a private company in charge of security at adjacent buildings housing Detroit City Hall and some county courtrooms after a man made it through with what authorities say may have been a handgun in a small briefcase.
Sgt. Michael Woody says Detroit police will speak Tuesday with representatives for Securitas to go over emergency plans.
Police gave the all-clear about 3 p.m. Monday, hours after the Coleman A. Young Municipal Center was placed on lockdown while police searched for the man who was allowed inside before guards realized he might have a gun.
Surveillance photos of the man and an X-ray scan that appears to show a revolver in his briefcase were released, but the man was not found.
Woody says police still were trying to identify him.
