US TV viewers following a high-speed car chase on live TV last Wednesday witnessed a shocking conclusion to the pursuit.

Dallas police were chasing a male suspect and the news helicopter captured the dramatic end to the chase as his vehicle smashed into the back of cars waiting at an intersection.

As the suspect tries to flee, a female motorist - who he had just hit - springs into action to confront him.

With the help of her passenger, they take down the man until the police arrive.

The brave woman's name is Jessica Liesmann, and speaking on The Dallas Morning News, she explained the reason for her actions.

“Everything happened too quickly. I was in a rage, just thinking he was going to pay for what he did,” said Jessica.

She now has interview requests from as far away as Japan and a local car dealership has even given her a new car to replace her damaged minivan.
