Bystander jumps into moving car to help fellow motorist

It was an incredible act of bravery and it was caught on camera.

Randy Tompkins was driving his truck in Dixon, Illinois when he spotted a car running a red light and heading into oncoming traffic.

The driver of that car was apparently suffering from a seizure behind the wheel. 

Tomkpins noticed something was wrong, threw his truck into park, leaped out of the truck and dove through the car's passenger window while it was still moving.

The video shows the car coming to a stop when Tompkins was able to put it into park, helping to prevent what could have been a terrible accident.

An officer traveling behind the vehicle caught the whole ordeal on dashboard camera. 

The officer ran to help and called for an ambulance.

Tomkins waited with officers until an ambulance arrived on the scene.

"We want to thank Tompkins for his heroism and for coming to a complete stranger's aid!" said the Dixon Police Department.
