An African-American attorney has filed a complaint after he says he was racially profiled and detained by a sheriffs deputy who thought he was a criminal suspect posing as his legal counsel in a Maryland courthouse.

Rashad James, an attorney for Maryland Legal Aid, filed a complaint with the Harford County Sheriffs Office on Tuesday requesting an investigation into the March 6 incident involving one of its deputies.

James had just appeared before a Harford County judge and won an expungement for his no-show client when a deputy who was in the courtroom asked to see his identification, according to his attorneys.
