Authorities are investigating an early morning carjacking of a Philadelphia mother and her teenage daughter that was captured on video that was later posted to social media.

Investigators say the pair were leaving their home on the 8900 block of Maxwell Place around 6 a.m. Monday morning when they were ambushed by an armed carjacker.

“It appears he was laying in wait,” Captain John Ryan told FOX 29’s Dawn Timmeny. “He rode a bicycle up there, left the bicycle behind, we have that.”

The disturbing video of the carjacking posted Instagram shows the mother pleading with the suspect as he threatens her and her daughter with a gun.
