Just hours before the winning the UFC Light Heavyweight Title Jon Jones and his trainers chased down a robber who broke into a woman's car. Yahoo!'s Steve Cofield has the story:

Jones, Jackson and Winklejohn pursued him on foot. Jones, the youngest of the group at 23, caught up to the robber and tripped him to the ground. Jackson told Yahoo!'s Kevin Iole that Jones "foot swept" the suspect.

With the robber on the ground, Jackson began yelling to his fighter to stay away. Once the trainers caught up to downed robber, Jackson jumped on him and applied an armbar. Winklejohn went for the other arm to make sure he didn't have a weapon. In the scuffle, the robber was bloodied. The trainers said some blood got on their pants. Shortly after, the police arrived to arrest the suspect.

Props go out to Jones, Greg Jackson, and Mike Winklejohn for the vigilante justice.
