PHILADELPHIA (CBS) – A woman went into premature labor following a crash in Philadelphia’s Overbrook section. The baby was born at just 25 weeks. Authorities say a possible drunk driver crashed into them.

The crash happened at Haverford and Overbrook Avenues, just before 3 a.m. Tuesday.

Security video shows the moment when a white Lexus slams into the back of a pickup truck just before 3 a.m. The pickup truck tried to brake when the Lexus came barreling through.

The impact of the crash caused the Lexus to overturn.

When medics arrived, they had to help deliver the baby in the cab of the pickup truck. Doctors are now working to help the baby pull through.

“It’s crazy, I don’t know where he came from, just ran into the back of us, I don’t know what happened,” said Yor’i El, the baby’s father. “The baby is alright, the mother is alright, I’m alright.”

The driver of that Lexus was taken into custody on suspicion of DUI.

The mother and newborn son are doing OK.
