He told the female drugstore employee to "touch his pants" -- where he held what the victim believed was a handgun, police said. Then he made her open the safe in the manager's office, stealing cash and several thousand dollars worth of stamps.
Now, Nassau County police are searching for the man they said robbed the Walgreens store on Jericho Turnpike in Mineola on Wednesday evening.
The suspect is believed to be about 5-foot-6, about 150 pounds, with a thin mustache, police said. He wore a camouflage jacket, blue jeans and a black baseball cap with white on it. Police said he fled on foot south on Roslyn Road.
Police said the robbery took place at 7:05 p.m. The female employee, 28, was uninjured.
Police said that after the suspect made the woman touch him he produced a demand note and ordered her to open the manager's office. She complied, giving the suspect access to the safe. Police said that, in addition to an undisclosed amount of cash, the robber stole "three-to-four-thousand dollars" worth of stamps.
Police are asking anyone with information about the robbery to call Crime Stoppers at 800-244-TIPS. All calls will remain confidential.
