HOLLYWOOD - Britney Spears is under investigation after she ran over a Los Angeles County Sheriff deputy's foot in her Mercedes-Benz.

Days after the troublemaker accidentally drove over a photographer's foot, Spears floored officer Stanley Mosk as she exited Los Angeles County Court following her custody hearing last week.

Sheriff's Department officials have filed a traffic-collision complaint, and now the LAPD is conducting an "active investigation" into the mishap, according to TMZ.com.

Mosk has been hobbling around court on crutches since the accident, and his superiors have been forced to reassign him to light duty.

A police source reveals officials are looking at the incident with a view to filing another hit-and-run charge against Spears.

The pop star narrowly escaped a hit-and-run conviction last month after agreeing to settle an August parking-lot accident out of court.
