R&B star Ray J has pleaded not guilty to groping and resisting arrest charges stemming from an alleged rampage at a Beverly Hills hotel in May (14).

Kim Kardashian's ex-boyfriend was taken into custody after a wild night at the Beverly Wilshire Hotel bar, where an inebriated Ray J reportedly kicked out the window of a police car and spat on a police officer. The singer told Tmz.com he smashed the window because he felt claustrophobic.

A Los Angeles District Attorney subsequently filed sexual battery, resisting arrest, assault and vandalism charges against the singer.

Ray J appeared in court on Tuesday (19Aug14) and pleaded not guilty to the charges of groping a woman and resisting arrest. He is due back in court for his misdemeanour case on 28 August (14).

If convicted of all counts, Ray J faces up to four years in county jail.
