A Las Vegas father has been arrested after he refused to break the window of his new car to save his dying toddler, according to authorities.

Sidney Deal, 27, got the attention of officers after he left his one-year-old daughter in the car with the keys inside on a hot Monday afternoon.

The officers offered to break the window, call a tow truck or get a locksmith but Deal declined and asked to call his brother.

After a few minutes, officers decided to smash the window, pulled out the unresponsive girl and she passed away at the scene.

The cause of death is pending, but authorities believe that she had been trapped in the car for more than a hour.

Detectives also interviewed Deal's brother who he called and the brother explained he was confused by the call and quickly headed to Deal's house.

Deal described in the call saying that he accidentally locked Sayah in the car and claimed that he had the airconditioning running.

After Deal's brother arrived, he immediately wrapped his shirt around his hand and offered to punch out the window, but Deal stopped him as he claimed he didn't have enough money to fix a broken window.

He instead asked his brother to call their mum to have her insurance company to send a locksmith.

Deal's girlfriend told police she also called the insurance company for him, but he told her to hang up after he didn't agree with the price quoted for a tow truck.

He was booked in the Clark County Detention Centre on one count of child abuse or neglect causing substantial bodily harm and is being held on $20,000 bond.
