Cameron Douglas, the son of actor Michael Douglas, was reportedly beaten in prison for informing on his drug suppliers.

Cameron Douglas, 34, is serving a nine-year prison sentence for dealing drugs, the New York Post reported. He originally was sentenced to 4½ years, but a judge tacked on an additional 4 ½ years after he was found to have drugs on him in prison, the report said. The son of Michael Douglas had been facing more jail time, but had the sentenced reduced for agreeing to testify against his heroin suppliers, identified as Mexican immigrant brothers David and Eduardo Escualera.

The captain of a crime family allegedly put a $100 bounty on Douglas, ordering inmates to rough Douglas up because he is a “rat,” the New York Post reported. The mobster’s identity was not disclosed, but a source told the newspaper that the captain “is the self-proclaimed ‘King of the Italians.’ They won’t tolerate rats, and Cameron testified against the people who gave him the drugs.”

Douglas was beaten severely, according to the newspaper article, and suffered a broken femur.  He reportedly told prison doctors that his injuries came from playing handball.

“He broke his femur, which is hard to snap, and had to have a rod inserted,” a source told the Post. “He told health services staff that he hurt them playing handball. You don’t break a femur playing handball.”

Douglas is addicted to heroin and was found to have somehow smuggled the drug into the prison for his use.

He also was sentenced for dealing crystal meth.

Douglas’ condition worsened after a prison doctor misdiagnosed his broken femur, and he developed a blood clot, the Post reported.

“She thought it was a sprain, so he wants to sue this woman. He’s still walking around on crutches two months later,” a source told the paper.

The source also said that Douglas has changed his appearance since he started serving time at the Metropolitan Correctional Center in Manhattan.

“He recently had his initials inscribed on his neck and big stars on his shoulders, with each year of his incarceration in each star: ’10, ’11, ’12. And he’s currently getting a scroll on his back.,” the source said of Douglas. “They are being done by his best prison pal, Billy Trent, and he’s paid over $1,000 so far for all the ink.”
