Authorities say a Baltimore special education teacher has been placed on administrative leave after being charged with human trafficking and prostitution.

Baltimore County police said Monday that 23-year-old Michael Brandon Osikomaiya was arrested last week.

Police said a 16-year-old girl posted an online ad for prostitution and an undercover detective contacted her to meet May 19 at a motel, where officers found her. Police say Osikomaiya is accused of being her pimp. The teenager wasn't one of Osikomaiya's students.

City school officials said in a statement that Osikomaiya was placed on administrative leave after the school system learned of the charges. He works at the public charter school NACA Freedom and Democracy II.

It's unclear whether Osikomaiya, who was being held on bond, has an attorney to comment on the charges.
