LOUISVILLE, Ky. (WDRB) -- Police are trying to track down a man suspected of robbing one taxi driver and cutting the throat of another. 

Investigators say the man has struck twice so far this week and was captured on surveillance video from inside the taxi. 

He's accused of calling cabs from Taxi 7 and Yellow Cab to an area near the intersection of of Utah and Arcade Avenues in south Louisville. 

"He knows the area," said LMPD Detective Nathan Blanford. "He picks the same block." 

Blanford says the the first incident happened between 4 a.m. and 5 a.m. Monday. When a Taxi 7 car picked the man up, he told the driver he needed to go around the block to pick up his dad. 

"He (the suspect) then leads him to a dead end, at which point he brings a knife up to his neck and asks for all of his money," Blanford said. 

The suspect got away with an undisclosed amount of money, and no one was hurt. 

But that wasn't the case Tuesday around 8:30 a.m. That cab also had a camera inside, which shows the suspect sitting in the back seat. 

"The cab driver for Yellow Cab decided he was going to fight with the suspect and subsequently, his throat was slit," Blanford said. 

Officials say the cab driver is expected to survive. Police are now asking people to help track the suspect down before he strikes again. 

"I'm sure with these pictures, somebody knows who it is," Blanford said. 

While Yellow Cab declined to comment on the case, Taxi 7 sent WDRB News a statement. 

It says in part: "Taxi cab drivers are hardworking people who desire to earn a living and support their families."

The statement goes on to say, "Taxi 7 is offering a $5,000 cash reward to anyone with the name, identity and location information that leads to the arrest of the perpetrator of these crimes." 

Police say the suspect could be between 18 and 22 years old. 

If you know who he is, you're asked to call 574-LMPD. You can remain anonymous.
