A man was arraigned Sunday on charges he stole money out of a street musician's tip bin in Nickels Arcade, Ann Arbor police said.

Adrian Buford, 40, is charged with unarmed robbery and conspiracy, police said.

He is accused of grabbing an undisclosed amount of money Saturday from the bin as a man was playing an ocarina, which is a flute-like instrument, police said.

Police are looking for another man for questioning in the case.
