WEST HAVEN, CT (CNN) -- A Dunkin Donuts employee in Connecticut stopped a robbery with the closest weapon available - hot coffee.

Police are looking for the man seen in this surveillance video Saturday night.

Authorities say the robber pulled up to the drive-though window and asked for change for a $100 bill.

When the worker refused, the man announced it was a robbery and tried to climb through the window.

The worker first tried to shut the window on him, before tossing a cup of hot coffee in his face.

When that didn't stop him, the clerk grabbed a whole pot of coffee and threw it at him.

The man got away empty handed.
