Police are looking for a man who stabbed a livery cab driver in the neck then carjacked him Wednesday morning in the Bronx. 

Police say 67-year-old livery driver Marcos Rivera-Peralta picked up the suspect at 179 Street and Boston Road, then drove the passenger to East 134th Street and Lincoln Avenue in Mott Haven. 

When they arrived, the passenger allegedly pulled out a knife and stabbed Rivera-Peralta in the neck.

The driver opened the door and fell out of the car.

He is now being treated at Lincoln Hospital where he's listed in serious condition. 

The livery cab was later found miles away in East Harlem.
