DUBLIN -- A Chase bank branch in Dublin was robbed on Wednesday and police are asking the public for help in locating the suspect.

The robbery took place Wednesday at the Chase bank branch at 4520 Dublin Blvd. and came just one day after a another bank, a Bank of America branch, was robbed on the same street a half-mile away.

No one was injured in either robbery.

Officers were called at 5:50 p.m. Wednesday to the Chase bank after a man entered the bank and handed the teller a note indicating he had a gun and wanted money, said Dublin police Lt. Herb Walters. No weapon was seen, but the teller complied with the note and the suspect left the bank with an undetermined amount of cash.

Police described the suspect as a white man between 5 feet 11 inches to 6 feet 1 inch tall, weighing 185 to 195 pounds and 20 to 30 years in age. He wore a blue sweatshirt jacket, black ball cap and bluejeans. The suspect also had a bushy beard, similar to a "Brian Wilson"-style beard, but it was possibly fake, Walters said.

Just one day earlier, a man robbed a Bank of America branch at 4250 Dublin Blvd.

About 11:45 a.m. police said a man entered the bank and handed a teller a note demanding all the money in the till. The man left the bank with an undisclosed amount of cash and was last seen heading east away from the branch, police said.

The man did not show a gun, police said.

That suspect is described as a black man between 6 feet 2 inches and 6 feet 4 inches tall with a thin build. He is in his late 40s to early 50s, with a scruffy grayish beard and dark hair. He was last seen wearing a black jacket, black gloves, bluejeans, glasses and a purple cap with the Toronto Raptors basketball team logo on it.

Anyone with information about either robbery is asked to call police at 925-556-4561 or 925-833-6696.
