Police are looking for a hat-wearing man who has robbed at least eight Long Island banks in the last three months.

The man is wanted in a series of bank robberies that dates back to early May. In each case, he approaches a teller, shows a demand note threatening violence unless he gets money, then flees with the cash.

The man is seen in surveillance video wearing a hat during each of the robberies; one of them has the president's face on it. Others are wide-brimmed.

He first hit a Chase Bank in West Hempstead May 5. Later that month he hit another Chase in Carle Place. In June, the suspect hit the same Chase he hit in early May, along with a different one in Merrick.

Police say the suspect robbed three banks in July -- a Capital One bank in Merrick and two more Chase banks, one in Bethpage and one in Farmingdale. He last struck July 23 at a Bank of America in Baldwin Harbor.

Anyone with information about the robberies is asked to call Crime Stoppers at 1-800-244-TIPS.
