Takaya Muto, a Lower House member who quit the Liberal Democratic Party over an alleged money scandal last week, has engaged in sexual intercourse with a 19-year-old male prostitute repeatedly since last November, the latest issue of weekly magazine Shukan Bunshun reported.

Muto met the man about 20 times and paid him ¥20,000 each time, the magazine, which hit the shelves on Thursday, claimed. Muto also had sex with him at an official residential complex for Lower House members in Tokyo about four times, according to Shukan Bunshun.

Muto is said to have denied the allegation.

The magazine also claims the 36-year-old lawmaker called the unnamed prostitute and demanded that he stop answering questions from the weekly.The magazine posted a screen shot on its website that it says depicts text-message exchanges between the two. In one of the messages, Muto apparently demanded the man serve as "a slave" to him and do whatever he wanted.

The sex scandal will probably damage the public image of the ruling LDP, which accepted Muto's letter of resignation last week without any investigation into the money scandal surrounding him.

According to the weekly, Muto has not returned about ¥7 million that he owes to six investors. Muto denied that allegation as well.

He raised ¥41 million from a total of 23 investors by allegedly saying he planned to buy unlisted stocks of a software company in order to log profits, according to the weekly.

Muto was an obscure lawmaker but drew great attention last month for using Twitter to describe student protesters who oppose two government-sponsored security bills as "self-centered and extremely egoistic."
