Brooke Mueller apparently has launched serious accusation against Denise Richards, claiming that Richards abused her twin boys Bob and Max as well as the "Twisted" star's daughters with Charlie Sheen. According to a TMZ report, police went to Richards' house on Tuesday night, November 26 to investigate the matter.

Sources say that Richards did not let them in because her daughters were in the house and spoke to them outside, instead. Talking to the authorities, Richards reportedly denied that she abused the children and called Mueller's claim "ridiculous" and "vindictive." Richards told the officers that she had not seen Bob and Max for two weeks and Mueller had no contact with her daughters.

Following the investigation, an insider tells Radar Online that Richards "is considering her options, including Brooke filing a false police report and/or civil action against her." The source adds, "There is NO evidence that Denise has ever physically or emotionally abused ANY of her children." The Los Angeles Department of Children and Family Services is also investigating the claim.

Bob and Max were removed from Mueller's care a few months ago because of her drug abuse. Richards then was appointed as temporary guardian when Mueller was in rehab. The boys gradually will be handed to their mother when she is deemed fit. Earlier this month, Richards sent a letter to the DCFS, saying that she wanted to give up the custody of the twin boys because they misbehaved. The court later decided that the boys' custody would be transferred to Mueller's brother, Scott.
