Listen to Ray J Radio on iHeartRadio

(TMZ) - The L.A. County D.A. has thrown the book at Ray J, charging him Monday with 10 CRIMES in connection with his drunken antics last May, reports TMZ. And get this - the D.A. charged Ray J with sexual battery even though cops say no such crime was committed.

According to TMZ, Ray J was at a bar at the Beverly Wilshire Hotel when he got rowdy, brushed up against a woman's bottom and was ordered to leave. Police told TMZ at the time it was NOT sexual battery because the contact was "incidental" - not intentional.  Apparently the D.A. begs to differ.

Ray J left the bar and then went nuts in an alcohol-fueled rampage.  He was arrested, kicked out the window of a cop car and spit on an officer.  Ray J told TMZ ... he kicked out the window because he was claustrophobic.

TMZ reports in addition to the misdemeanor battery charge, Ray J was charged with 4 counts of resisting arrest, 3 counts of assault and battery and 2 counts of vandalism ... all misdemeanors.
