A criminal complaint filed against Bill Cosby on Tuesday includes a detailed and explicit account of his history with Andrea Constand, the woman accusing him of sexual assault .

The disturbing allegations are contained in an 18-page affidavit filed by police in suburban Philadelphia. Constand described taking pills Cosby gave her at his home in 2004, and told police that she soon she slipped into a drug-induced delirium during which Cosby fondled her and forcibly placed her hand on his penis.

The encounter ended with an awkward exchange after she awoke at 4 a.m., she said.

"Cosby gave her a muffin, walked to the front door, opened it and said 'Alright,'" according to the affidavit. "The victim told investigators she left without saying anything."

A Cheltenham Township sergeant and two Montgomery County detectives filed the affidavit to get an arrest warrant for the 78-year-old comedian. A judge approved the warrant and Cosby turned himself in on Wednesday to be arraigned on a single charge of second-degree aggravated indecent assault.

More than 50 women have come forward to accuse Cosby of indecent behavior ranging from unwanted kissing to rape and other forms of sexual abuse. Constand was one of the first to complain to law enforcement. She also sued Cosby, and in 2006 they finalized a settlement out of court.

This document provides a fuller picture of her accusations, including two occasions prior to the alleged assault when Cosby aggressively tried to initiate a sexual relationship with her. It also covers his denial to authorities, the decision by a previous Montgomery County district attorney not to file charges and the recent discovery of new evidence that reopened the case.

This is what Constand told police about Cosby, though it's only a small portion of the entire affidavit.
