A man facing rape charges in a case that also involves former NFL safety Darren Sharper has turned himself in to New Orleans police.

Police say 26-year-old Erik Nunez was booked Friday morning with two counts of aggravated rape, stemming from alleged assaults last September in New Orleans.

Police issued warrants for Sharper and Nunez in the New Orleans case Thursday.

Sharper also is under investigation in sexual assault cases in Florida, Nevada and Arizona and has pleaded not guilty to rape charges in Los Angeles.

If convicted of aggravated rape in Louisiana, Sharper and Nunez would face life imprisonment.

Sharper retired after the 2010 season, after 14 years in the NFL. He's an analyst for the NFL Network, which has suspended him indefinitely without pay.
