A woman told the police that she had a child with the casino mogul Steve Wynn after he raped her, while another reported that she was forced to resign from a Las Vegas job after she refused to have sex with him.

The Associated Press on Tuesday obtained copies of police reports recently filed by the two women about allegations dating to the 1970s. The police in Las Vegas said this month that they had taken the statements after a news report in January revealed sexual misconduct allegations against the billionaire.

The allegations are the latest leveled against Mr. Wynn. He resigned as chairman and chief executive of Wynn Resorts on Feb. 6, less than two weeks after The Wall Street Journal reported in an in-depth investigation that a number of women said he harassed or assaulted them and that one case led to a $7.5 million settlement.

Mr. Wynn has vehemently denied the misconduct accusations the newspaper reported, and he attributed them to a campaign led by his ex-wife, Elaine Wynn, whose lawyer has denied that she instigated the news article.
