Paris Hilton's boyfriend Cy Waits allegedly ran over a female photographer's leg with his Bentley in West Hollywood Wednesday night then fled the scene. The collision happens around 0:28 in the video below.
Cy was placed under citizen's arrest, TMZ reports. Paramedics took the photographer to the hospital and at some point Cy returned and talked with police.
After the accident, Paris tweeted, "Lovely evening with friends and family ruined by aggressive paparazzi. They are literally insane!"
An hour later she wrote, "Gong to bed. Sweet dreams everyone. Love Paris xoxo."
Cy and Paris were arrested in August for cocaine possession.
