The incident happened in Riverhead, at the 7-Eleven store on Old Country Road, at around 1:45 a.m. Monday, Nov. 4.
Riverhead Town Police said a masked man approached the counter and requested a pack of cigarettes before demanding that the female clerk open the cash register.
When the employee refused, the man jumped over the counter and pulled out what appeared to be a gun covered with a cloth.
At that point, a male employee intervened and attempted to subdue the suspect. After a brief struggle, the suspect fled with a pack of cigarettes and a bottle of Gatorade.
Police described the suspect as a Black man, approximately 5-foot-10, wearing a dark jacket, a medical mask, gloves, and black and white checkered pants.
Anyone with information is asked to contact the Riverhead Police Department at 631-727-4500.
