Two individuals were arrested on Friday afternoon following a robbery and assault incident at Evolve Smoke Shop in Hicksville.
Detectives say 20-year-old Cristian Zuluaga, of Hicksville, entered the store on Oyster Bay Road at around 3 p.m. and attempted to take items without paying.
When a store employee attempted to stop him, he punched him in the head several times.
Authorities say 18-year-old Margarita Bournias, of Syosset, entered the store and became involved in the altercation. She pushed the worker and threw a coffee mug at his head.
The two suspects proceeded to flee, but police say they were arrested after returning to the scene a short time later.
The employee was evaluated at the scene and refused further medical treatment, according to authorities.
Police say Zuluaga and Bournias face charges for robbery and assault. Bournias is also facing weapons charges.
