Evansville Police are looking for a man they say robbed a Mexican restaurant Friday night. Police say an employee working the carry-out window at the Hacienda on First Avenue spotted a man entering the building with a brown paper bag covering his mouth. They say the suspect showed the employee a gun and demanded money out of the cash register. When she got the drawer open, the suspect grabbed the cash and ran. It is unclear how much money the suspect got away with. If you have any information about this case you're asked to call Evansville police.
