Cops Will Refer Lindsay Lohan Case to D.A.

Lindsay Lohan is about to go back to familiar territory -- the L.A. County D.A. -- because we've learned cops are sending the case involving an alleged hit-and-run by the actress to prosecutors.

The manager of the Hookah Lounge on Hollywood Boulevard claims Lindsay was leaving a nearby club March 14 when her car struck him ... and he claims she took off without leaving any info. Lindsay says the guy is making it all up and her car never came near the guy.

The manager's story is hinky to say the least ... lots of holes. Nevertheless, we're told the LAPD has completed its investigation and will send the file to the D.A. for review.

Sources close to the investigation tell us, after looking at videos and conducting interviews, there isn't enough evidence to prove a crime, but the D.A. will have the final say.
