LANCASTER - Police are investigating an aggravated robbery that occurred at the Shamrock Bingo parlor, 3800 N. Dallas Ave., early Saturday morning.

Employees reported they were closing as the last customers were leaving the business at about 12:30 a.m. when they were confronted at the door by two men wearing ski masks, gloves and dressed in dark clothing.

The gunmen forced two employees and three customers back inside the business, bound their hands and proceeded to take an undetermined amount of money from the business and from the individuals.

One of the gunmen physically assaulted one of the employees, who was taken to Medical Center at Lancaster for treatment of non-incapacitating injuries.

Detectives were gathering evidence and interviewing the victims through the early-morning hours, according to police, who said the victims described the gunmen as a black male and a white male, possibly of Hispanic descent.

Anyone with information related to this offense is asked to call the Lancaster Police Department at (972) 218-2700.
