Police are searching for the person who stabbed a livery cab driver in the Bronx late Sunday night.

The cab driver was heading south on Hering Avenue in Allerton around 11 p.m. when his Lincoln Town Car crashed near Burke Avenue.

Witnesses say they saw two men run out of the car toward the Eastchester Garden Houses.

The middle-aged driver had stab wounds to his stomach and chest. He was taken to Jacobi Medical Center in serious condition.

An EMT and her military veteran husband saw the commotion and went outside to provide first aid.

"I just literally snatched the shirt off my husband's back and applied pressure to his wounds and kept an eye on his pulse, because he had kind of crumpled to the ground in a weakened state," said Good Samaritan Vickie Callender. "He wasn't unconscious. He was incoherent and he wasn't really talking or saying anything and he had moments where it looked like he lost breath and then he caught breath again."

Callender says that before losing consciousness, the livery cab driver told her husband that the two passengers he had just picked up in front of a 24-hour deli on East Gunhill Road had tried to rob and kill him.

Her husband said that the driver told him that after crashing into a white truck parked on Herring Avenue, he got out and tried to run.

"He jumped out they jumped out behind him," said Callender. "They stabbed him in the stomach behind the car."

The driver remains in serious condition.

In just the last few weeks there have been at least two other attacks against livery cab drivers. A driver was shot in the face in Queens on August 22nd, and four days later another driver was attacked in the Bronx and his livery cab stolen.

Anyone with any information is asked to call Crime Stoppers at 1-800-577-TIPS.
