U.S. reality Tv star Camille Grammer's ex-boyfriend has walked away from charges after she accused him of attacking her in a Houston, Texas hotel room last year (Oct13).

Grammer, the ex-wife of actor Kelsey Grammer, accused Dimitri Charalambopoulos of leaving her bruised and battered following an alleged altercation and she won a three-year restraining order against him.

But, in court on Wednesday (28May14), the members of a grand jury ruled there was not enough evidence to proceed with the case.
