A dispute between two cabbies turned violent on Saturday night.
The police said that Mohammed Sharief, 47, assaulted a 39-year-old man with a metal tire jack. A witness said that two cab drivers confronted each other on First Avenue and Sixth Street, some time around 9:45 p.m., and one of them struck the other in the head.
The confrontation was loud enough to attract the attention of customers inside nearby stores and restaurants. Mr. Sharief was arrested at the scene and later charged with assault and criminal mischief.
