An upcoming documentary on late Libyan dictator Muammar Qaddafi reveals shocking new details of the ruler’s brutal regime, including keeping his enemies’ corpses in freezers and maintaining a secret sex den on the Tripoli University campus where he’d rape coeds reports The New York Post.

In Christopher Olgiati’s “Mad Dog: Inside the Secret World of Muammar Gaddafi,” the director uncovers the leader’s depraved sexual predilections, barbaric revenge tactics and lifestyle he led making $1 billion per week, by interviewing those who were closest to him.

The Showtime doc airs this coming Friday, days before a Libyan trial of Qaddafi’s sons, Al-Saadi and Seif Al Islam, and his spy chief, Abdullah Senussi.

Among those interviewed, Olgiati tracked down Qaddafi henchman Frank Terpil, a rogue CIA agent in Cuba after being sentenced to 53 years in Manhattan State Supreme Court for illegal arms dealing. Terpil, according to the doc, ran what Qaddafi called his “Murder Incorporated,” a “murder for hire” team with fellow former CIA operative Edwin Wilson.

Terpil recalls one hit in which the leader demanded that the head of his intended target be brought to him in a cooler. “I was in Geneva with Wilson. [A Qaddafi relative] opened up a letter of credit for a million dollars for [the target’s] demise, on the caveat that his head be delivered back in a cooler to Libya so Qaddafi could actually look at the results of the work,” he says.

Olgiati and producer Michael Chrisman also visited the dictator’s sex den where he would rape women after his lengthy speeches at the university. The lair contains a bed, Jacuzzi and area where they women were examined for STD’s. Surgical instruments, rubber masks and anaesthesia were also found.

Olgiati described Qaddafi to the paper as, “utterly charming, utterly ruthless and stupendously rich. He was driven solely by his lust for power.”
