Brian Nadeau, an FBI agent with experience investigating public corruption, will become the Baltimore police deputy commissioner in charge of the Public Integrity Bureau, Commissioner Michael Harrison announced Thursday.

During a brief press conference at police headquarters, Harrison said Nadeau "has served the region and country with distinction."

Nadeau is assistant special agent in charge at the FBI's Baltimore field office. He previously headed the FBI's public corruption unit.

It is the second time Harrison has attempted to fill the position. In May, he selected former city prosecutor Michelle Wilson to oversee internal affairs. Wilson, who now works for Maryland Attorney General Brian Frosh, had recently accused State's Attorney Marilyn Mosby of perjury in a wrongful termination suit filed by a former colleague. Two days after Harrison announced Wilson would be joining the department, her name was withdrawn.

Harrison said his office took their time to find the right match for the opening.

"It is extremely critical. It is as important as training, policy," Harrison said. "Discipline is very important."

Harrison said it's also important that the bureau be able to bring "justice" and value both complaints from citizens and the long careers of city officers.

Harrison said he has received positive feedback from Mosby on the hire.

Nadeau is set to begin his job with city police in September. He could not comment at length during the press conference, noting he is still a federal employee.
