A woman's dog was seriously injured in New York Monday after a thief stole her Range Rover with the pet inside and attempted to throw it out of the window on the freeway.

Nassau County Police said the theft took place at the BP gas station at 91 West Jericho Turnpike in Mineola around 2:45 p.m. Monday. 

While the 60-year-old woman was pumping gas into her white 2020 Range Rover, an unknown man approached her car on the opposite side, slipped into the driver's seat and took off heading west onto the Jericho Turnpike.

The man in question is described as being of thin build. He was wearing a black hoodie, white/black/gray sneakers, black gloves and a black ski mask.

The woman's 1-year-old Cavachon Bichon dog was inside the car when it was stolen, along with an assortment of credit cards and her purse.

Witnesses told police the thief tried to throw the dog out of the vehicle in the area of the Jericho Turnpike and Mineola Boulevard, but the collar got caught, dragging the dog down the road.

Police said the dog was eventually able to free itself from the car as it continued westbound. A passerby rendered aid to the small dog and called 911.
