Lindsay Lohan was arrested for leaving the scene of an accident early this morning after allegedly clipping a pedestrian in downtown Manhattan .
.. TMZ has learned.
Law enforcement sources tell TMZ, Lindsay was pulling in to park her Porsche Cayenne near the Dream Hotel in downtown NYC when -- at a very low speed -- she allegedly hit the knee of a 30-something year old guy. That was around shortly after midnight.
We're told one of Lindsay's passengers in the SUV got out and checked the vehicle for damage, and then LiLo and co. went inside the hotel.
