Dramatic video captured the moment a fast-acting Florida cop arrested a carjacker who drove off in a father’s pickup truck with two young kids still inside.

The father flagged down Deputy Jonathan Pazmino Alvarez in Tampa at 6:42 p.m. Monday after his vehicle was stolen along with his two children, ages 4 and 8, the Hillsborough County Sheriff’s Office said.

“Alvarez immediately pursued the 2011 white Chevrolet Silverado, and without losing sight of the vehicle, was able to conduct a traffic stop within just a few minutes,” it said in a statement.

“Stop the truck, now! Pull into the parking lot,” the deputy yells as he approaches the alleged carjacker, identified as Kevin Smith.

One of the kids yells out that the man had stolen the vehicle.

“That’s not my dad,” the child in the passenger seat says.

Alvarez tells the driver to get out of the car — but the man says, “Not me!”

“Let me figure it out. I don’t know what’s going on,” the deputy says as he orders him to hand over the keys.

The driver then whines that he doesn’t want the cop to slug him.

“I’m not gonna punch you, bro,” Alvarez says before placing the suspect in handcuffs.

Smith has been charged with two counts of felony kidnapping and one count of grand theft of a motor vehicle, police said.

The sheriff’s office said Smith has a criminal history dating back to 2003 in Hillsborough County.  

“This situation could’ve been a lot worse had it not been for the swift action taken by Deputy Pazmino Alvarez,” Sheriff Chad Chronister said.

“He halted what could have been an otherwise terrifying situation for any parent. Thanks to him, two children are safe and in the arms of their loved ones today,” he added.
