Spencer Clawson

If you thought the banter among the Big Brother houseguests couldn't get any worse this season ... think again.

Contestant Spencer Clawson is under investigation by his hometown police department after he went on an eye-popping tangent about child pornography this week. It's pretty clear that Clawson intended the comments as a joke — he had grabbed the microphone of fellow contestant McCrae and was pretending to be McCrae — but authorities were apparently not amused.

"I like to [masturbate] to child porn," Clawson said. "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."

The remarks grabbed the attention of the Conway Police Department in Clawson's home state of Arkansas, which is now investigating the incident, TMZ reports.

" Due to the nature of the comments, our department moved quickly to look into the matter," the department told TMZ in a statement. "At this time we haven't found that any criminal act was committed."

Big Brother contestant fired after offensive comments

Clawson was also one of the Big Brother contestants who came under fire earlier this season for making racist and homophobic comments about other contestants. His employer, Union Pacific, issued a statement formally reprimanding him for those comments and the company seems to be equally offended by his latest remarks.

"Due to the volume of feedback Union Pacific has received from the public about Spencer Clawson's August 5 comments on the CBS reality show Big Brother 15, the company wants to reiterate that it has taken all the action it can under the Collective Bargaining Agreement until Mr. Clawson is released from the show," the company said in a statement. "Mr. Clawson took an unpaid leave of absence to participate on Big Brother 15. Union Pacific has notified law enforcement of Mr. Clawson's August 5 comments."
