Lubemba was taken into the custody. During a custodial search, deputies found that he had in his possession three, fully-loaded magazines, containing 15 live 40-caliber, hollow-point rounds, a 4.5 inch knife, an ASP baton, pepper spray, and a pair of handcuffs.

He was charged with aggravated unlawful use of a weapon and with impersonation of a peace officer.

He was convicted in March 2011 of carrying/possessing a firearm.

Lubemba is scheduled to appear in bond court today at the George N. Leighton Criminal Court Building.

Sheriff Dart reminds the public that the defendant is presumed innocent until proven guilty by the government in a court of law.
