LAS VEGAS -- Las Vegas police have recommended that former heavyweight champion Mike Tyson be charged with sexual assault in two cases, a prosecutor said Friday.

Prosecutors and police met for two hours Friday to discuss a September complaint by a Las Vegas woman and a November 2000 allegation from another woman identified by police as being in her 20s and an out-of-state resident. The second case was not reported to police until December.

"They've done a very thorough investigation," Chief Deputy District Attorney Doug Herndon told The Associated Press.

He said police are seeking arrest warrants from prosecutors for Tyson on multiple counts of sexual assault in each case.

Herndon said he requested police submit information about Tyson's 1991 rape conviction in Indiana and a sexual battery allegation made by a woman last year in Big Bear, Calif. Tyson was cleared of the allegation in California.

Herndon said it would be several weeks to a month before prosecutors decide whether to charge Tyson.

Messages left with a Tyson spokesman and lawyer were not immediately returned, though representatives for the former heavyweight champion have said he has cooperated with authorities.

"I'm hopeful the Clark County district attorney's office will conduct a diligent and thorough review of the charges and dismiss this," Tyson attorney Darrow Soll said earlier this week.

On Tuesday, the Nevada Athletic Commission voted 4-1 to refuse Tyson a license to challenge heavyweight champion Lennox Lewis on April 6 at the MGM Grand hotel-casino.

Police began investigating Tyson in mid-September, after a Las Vegas woman went to a hospital with injuries that she said were suffered when the boxer raped her at his home.

Herndon said the woman had been in a six-month romantic relationship with Tyson.

Police searched Tyson's $1.3 million home for more than six hours on Sept. 26 and confiscated several boxes of material, including videotapes, sheets and towels.

The second woman went to police Dec. 28 and reported that she also had been attacked at Tyson's home in November 2000. The woman initially went to police near her home and reported that she had been raped, Las Vegas investigators said.

The police department the woman first contacted never reported the case to Las Vegas police, who have not identified the first agency.
