WOODBURY - Police say there could be another serial bank robber on the loose in Suffolk County.

They say a man with facial hair and a shaved head robbed the Capitol One Bank in Deer Park last Saturday.

Detectives told News 12 Long Island that they're investigating whether this same man was behind Thursday's holdup at the Bethpage Federal Credit Union on Route 109 in Farmingdale and Tuesday's robbery of the Bank of America in Commack.
