has claimed Charlie Sheen

Brooke - who is currently divorcing the troubled 'Two and a Half Men'actor and embroiled in a bitter custody battle over the couple's 23-month-old twins Bob and Max - revealed she is worried the actor is "currently insane" and said she is worried for the safety of their children.

In court documents Brooke filed to obtain a restraining order against Charlie and obtained by RadarOnline, she said he "threatened to stab my eye with a pen knife ... spit on my feet [and] punched me in the arm".
"I'm very concerned that [Sheen] is currently insane. In addition, last week [Sheen] insisted that I travel with [him] and his two girlfriends to the Bahamas. I did not want to go, however, I was afraid I would enrage [Sheen] if I did not go. He was in a rage because he could not find his checkbook.
