He wore a New York Yankees T-shirt -- and a Boston Red Sox baseball cap.

Now, Suffolk County police are asking for your help in locating the man with a salt-and-pepper goatee who they said is wanted in connection with two bank robberies, and one unsuccessful attempt, so far this month in East Farmingdale, Huntington and Deer Park.

Police said Pattern Crime Unit detectives are conducting an investigation into the incidents, asking anyone with information to call Crime Stoppers at 800-220-TIPS.

All calls will remain confidential -- and callers are eligible for a cash reward of up to $5,000 for information leading to an arrest in the case.

The first robbery took place at a TD Bank branch on Route 110 in East Farmingdale on July 7 at about 12:15 p.m., when the man entered the bank and demanded a teller give his cash.

The teller complied and the robber, said to be about 5-foot-6 or 5-foot-7 and in his late 30s or early 40s fled.

Then, police said, the man struck again Tuesday.

First, he entered the People's United Bank branch on East Main Street in Huntington at 11:51 a.m., approached a teller and made "multiple demands" for cash, police said, but was rebuffed and fled empty-handed. Twenty-five minutes later, police said, the man entered a TD Bank branch on Deer Park Avenue in Deer Park, demanded cash, got it and fled the scene on foot.

Surveillance footage from one of the incidents shows the man wearing a white T-shirt that reads: New York Yankees, Established 1903. He also is wearing a red Boston Red Sox baseball cap.
