A retired D.C. police officer pleaded guilty in a hit-and-run collision with a bicyclist that was caught on camera.

On Aug. 31, 2011, prosecutors said, John W. Diehl, 57, pulled alongside the victim and cursed at him for being in the middle lane of the 3000 block of Rhode Island Avenue NE. Diehl then changed lanes and clipped the cyclist, causing the victim to crash. Diehl kept driving. The bicyclist suffered an injury to his shoulder.

The video was caught on camera by the cyclist's helmet-mounted camera.

Diehl pleaded guilty Tuesday to leaving the scene after a collision and destruction of property. The plea deal calls for a deferred sentencing agreement that allows Diehl to withdraw his guilty plea if he completes certain conditions, including performing 25 hours of community service, undergo counseling for anger management, and complete a drivers' safety course.
