ISLAND FALLS — Maine State Police are investigating a bank robbery in the Aroostook County town of Island Falls.

Troopers are looking for a man who robbed the Katahdin Trust Company shortly before noon today.

Authorities say the man did not show a weapon and was wearing all black when he demanded cash from a teller and fled with the money in a blue bag that he had brought with him.

Police say only two bank tellers were in the building at the time.

Police believe the robber got away in a vehicle that he had parking between two potato houses near the bank.
