CHICAGO — A security worker walked into the Daley Center wearing body armor and carrying a loaded semi-automatic pistol Tuesday morning, the sheriff's office said.
Lumani Lubemba, 32, was charged with aggravated unlawful use of a weapon and impersonating a Chicago police office in the incident, according to the Cook County Sheriff's Office and court records.
About 9 a.m. Tuesday, he allegedly walked into the government building dressed in a blue uniform and black body armor before approaching a sheriff's deputy and saying that he was there to sign in his weapon.
Lubemba was carrying the handgun on his right hip, under a black jacket, officials said.
After being taken into custody, Lubemba was searched. Deputies allegedly found three fully loaded magazines, a 4.5-inch knife, a baton, pepper spray and a pair of handcuffs.
Though Lubemba works in security, he is not authorized to carry a gun, according to the sheriff's office and prosecutors.
Lubemba appeared in bond court Wednesday where a Cook County judge set his bail at $250,000.
Lubemba was arrested in 2010 on gun charges and for impersonating a police officer. In that case, he was convicted of carrying a firearm and was sentenced to one year of probation, according to court records.
