King County Sheriff's detectives are looking for the man who robbed a Chase Bank Friday, Sept. 4, who they are calling "low key."

According to the sheriff's office, the man was so low key, other employees and customers didn’t know the bank was robbed until the teller called 911.

The robber came into the bank, located at 1616 S.W. 100th St. in White Center at about 2:30 p.m. He walked up to a teller and said he wanted to make “a withdrawal." The teller said he would need a withdrawal slip and directed him to the forms table.

The man went to the table and appeared to be filling out the slip. The suspect got back in line and eventually made his way to the original teller. This time he leaned into the teller’s window, and said in a deep, soft voice that this was a robbery, according to the sheriff's office.

The man was given cash and he quietly left the bank. No gun was seen and there was no note.

The robber is a black male about 45 years old, 5 feet 8 inches tall and 175 lbs. He had a mustache and goatee and wore jeans, a brown fleece-type zippered coat and a brown fabric hat with a short bill.

If anyone recognizes the man they should call the King County Sheriff's Office at (206) 296-3311 (24 hours) or 911.
