Olivier Martinez -- No Criminal Charges in Car Seat Assault Case

Olivier Martinez has dodged a bullet ... he will NOT be criminally prosecuted for slamming a baby car seat into an airport employee at LAX.

Law enforcement sources tell TMZ, the L.A. City Attorney will conduct an office hearing where Martinez and the LAX employee will tell their sides, and then Halle Berry's husband will probably get a warning and the case will be closed. The hearing officer could make anger management part of the deal.

You'll recall, Halle, Olivier and Nahla had just arrived at the Tom Bradley International Terminal in January when the employee tried playing amateur photog, which pissed off Olivier. He took the empty car seat and rammed it into the employee, causing him to fall backward.
