Authorities made an arrest Friday after a month-long investigation of an aggravated robbery of a Subway last month in Whitewater Township.
The gunman, identified as Corey Sullivan, held up the restaurant at 4135 State Route 128 July 12, according to police.
Sullivan entered the business around 8:15 p.m. and demanded money from the cash register, according to the Hamilton County Sheriff's Office.
One employee complied while a second worker fled the restaurant.
Police said Sullivan had taken off out the back door, but he left with an undisclosed amount of cash.
No customers were inside the business when it was held up. No one was hurt.
According to officials, Sullivan was charged with aggravated robbery and was transported to the Hamilton County Justice Center.
