Riverhead detectives released photos on Thursday of one of three masked robbers who held up Barth's Drug Store a week ago, and a cash reward has been offered for information leading to any arrests in the incident.
Riverhead Town Police said that last Wednesday around 6 p.m., three suspects wearing masks, one armed with a handgun, entered the store and demanded cash and prescription drugs from employees.
Holding employees and customers at gunpoint, the trio was wearing hooded sweatshirts and masks, and fled through the rear door following the hold-up.
Police said a parked vehicle was seen with its headlights on near Barth's rear door facing the building, and another was seen driving easterly through the parking lot.
Police are asking anyone with information about the crime to call 1-800-220-TIPS. All calls will be kept confidential, and information leading to an arrest could offer up to $5,000.
The robbery was the third in recent weeks during which suspects were armed and wearing masks. One robbery occurred at the Spirit Halloween store in October; held up a Valero in Riverside.
