THE BRONX - Police are searching for a man they say assaulted and robbed a cab driver on Thursday.

Authorities say a man got into a cab in the Bronx and traveled to Brooklyn, where he paid his cab fare with a $100 bill.

However, when the cab driver went into a store to get change, the suspect allegedly followed him and took back the money.

Police say the suspect then punched the driver, stole more money from his pocket and ran off.
