Palatine police and FBI officials are searching for two people who robbed a bank this afternoon in the northwest suburb, officials said.



The robbery happened at the Chase Bank branch, 825 W. Euclid Ave., Palatine police and FBI officials said.



Police said that at 3:10 p.m., an Inverness police officer was flagged down and told that the bank was being robbed.



After the officer approached, he spotted a person fleeing southwest from the bank and into a residential neighborhood. Palatine police along with police from other jurisdictions set up a perimeter and used K9 units and a helicopter from the Cook County sheriff's police to search the area but were unsuccessful, officials said.



Police said witnesses in the bank told them that two males both wearing black sweatshirts with the hoods up and black ski masks, entered the bank. The males were wearing white gloves and black shoes.



One of the robbers climbed over the teller counter and accessed the cash drawers. The second person stood in the lobby with his hand in his pock to imply he had a weapon. Both fled the bank together.



The men were between 5-feet-9 inches and 5-feet-10 inches tall.
