Spencer Clawson, a “Big Brother 15” contestant who was last month under fire for making abusive comments to a houseguest, has once again come under the radar -- this time, for making jokes about child pornography on the live feed of the reality show.

E!News reported that, on Monday, Clawson was overheard talking to fellow houseguests Amanda Zuckerman and Andy Herren, saying, "I like to beat off to child porn. Did I ever tell y'all about that? I love it. Beating off to child porn is my favorite thing there is. I love it when they're around 3 or 4 years old. My favorite ones are when you can tell they're in a basement."

Both Zuckerman and Herren looked uncomfortable, and they quickly changed the subject.

Reportedly, Clawson was pretending to be fellow contestant McCrae Olson when he joked about child pornography. But, law enforcement officers in Clawson’s home state of Arkansas are already probing his past.

"The Conway Police Department was alerted to comments made.  Due to the nature of the comments, our department moved quickly to look into the matter.  At this time we haven't found that any criminal act was committed," Chief AJ Gary from the Conway Police Department in Conway, Ark., told TMZ.

Reacting to the comments made by Clawson, CBS, which airs the reality show, issued a statement distancing itself from the views expressed by its contestants.

“At times, the Houseguests reveal prejudices and other beliefs that we do not condone. We certainly find the statements made by Spencer on the live Internet feed to be offensive,” the network said, in a statement cited by E!News.

Last month, Clawson grabbed headlines when he called Hitler a gifted speaker, and called another houseguest "Kermit the F***."

Following this, Union Pacific, Clawson’s employee, issued a statement hinting that Clawson might be asked to leave.

"The values represented by Spencer Clawson's comments during the Big Brother show do not at all align with Union Pacific's values. Mr. Clawson is on unpaid leave of absence while participating on Big Brother. Union Pacific does not condone his comments,” the company said at the time, in a statement on its website. “Union Pacific is acting in accordance with Collective Bargaining Agreement terms regarding Mr. Clawson.”
