The Broward Sheriff's Office said it is questioning the driver of a car that struck a woman and her grandson Friday afternoon in Dania Beach.
The grandmother was taken on a trauma alert to Memorial Regional Hospital with serious head injuries after the incident at Dania Beach Boulevard and U.S. 1, authorities said.
The child, his mother and grandmother were trying to cross the street when a car hit him and his grandmother. The boy was also taken to the hospital, the BSO said, but he is going to be fine.
The mother was not hit, but she became so upset that police temporarily placed her in handcuffs so she would not interfere.
Investigators are now trying to determine whether the driver had the green light, the BSO said.
