An infant has died following a serious crash involving an ambulance in Philadelphia's Frankford neighborhood on Sunday morning. According to police, the driver of the ambulance, a 51-year-old man, will face charges, including DUI and related offenses.

The crash happened at the intersection of Torresdale and Harbison avenues, around 5:15 a.m. According to police, a private ambulance, transporting an infant and a mother, was speeding down Torresdale Avenue, but the ambulance's emergency lights and sirens were off. 

As the ambulance ran a red light, a Honda Accord heading eastbound on Harbison Avenue struck the driver's side front door of the ambulance, police said. 

The impact of the crash caused the infant and mother to be ejected from the vehicle's front windshield. Police said both were found on the road. 

CBS News Philadelphia was at the scene where a heavily damaged ambulance was on its side, and another vehicle had crashed into a nearby building. 

The infant and mother were taken to the hospital, where the baby was pronounced dead. The mother is currently in critical condition after suffering severe head trauma. 

The ambulance driver was also taken to the hospital. The driver of the Honda refused medical treatment at the scene. 

Police said they had initially been called to a home on the 6600 block of Ditman Street for a report of an unresponsive infant, but before police arrived, the infant and mother had left in the private ambulance. 

The crash remains under investigation.
