It all began when a police officer spotted a passenger riding in a Tennessee SUV without a seatbelt on. The officer then pulled the vehicle over and began to talk to the driver.

The incident ended with the driver facing serious robbery and drug charges in an incident about 125 miles east of Clarksville.

The Nashville man, 26, behind the wheel of the Mercury SUV appeared to be "very nervous," according to a police report of the incident in Cookeville.

As the man spoke with the police officer, he reportedly gave the officer more than one name and began making a cell phone call during the investigation.

The officer walked around to the other side of the vehicle, apparently to talk to the passenger, and saw the driver allegedly removing a small plastic bag from his mouth. The officer then examined the bag and determined that it contained crack cocaine.

At that point, he said he was placing the driver under arrest.

But as the man exited the vehicle, he reportedly pushed the officer out of his way and ran away toward a Cookeville residential area.

The cop called for backup, including a K9 unit, to help track the suspect down.

The man was soon found behind a nearby business building. An officer reported that the man rushed at him, but when warned of the police dog, the man stopped, raised his arms and surrendered.

The man was apparently wanted on for a Nashville robbery. He was booked on that charge, as well as possession of crack cocaine, resisting arrest and evading arrest.
