A 74-year-old grandmother has broken down in tears recalling how she was allegedly sexually harassed by NFL star Derrius Guice in December 2017.

Gloria Scott made the claim during a Louisiana Senate hearing on Friday, asserting that Guice made vulgar comments to her while she was working as a security guard at the Mercedes Benz Superdome in New Orleans.

At the time, Guice was a star football player for Louisiana State University.

Friday's Senate hearing pertained to broader claims that LSU has mishandled its responses to student allegations of rape, domestic violence and assault.

'I'm not just here for myself,' Scott sobbed as she spoke to lawmakers.

'I just had to come here today and let you all know that LSU hides a lot of things. A whole lot of things are going on on that campus. He scarred me.'

Scott stated that Guice, who was aged 20 at the time, approached her with a group of his friends while she was working a shift at the stadium.

He allegedly said to her: 'I like to f**k women like you, you older women, because y'all know y'all like us young men to f**k y'all'.

'You know you want this body,' Guice is alleged to have said while rubbing himself up and down and touching his genitals.

The football player's friends were purportedly standing at his side laughing.

Scott told lawmwakers that she told Guice to show some respect given that she was a grandmother.

'My grandsons are not like this,' Scott says she told Guice.

'F**k your grandsons. They don't know nothing, you and I are going to the hotel so I could f**k you,' Guice is accused of responding.

Scott says the harassment continued for about four minutes before Guice and his friends left.

'I was so hurt, and I was so nervous and upset,' she told the Senate hearing.

'In all my life, I'd never had a man or child talk to me so disrespectful like he did.'

Four days later, Scott reported the incident to LSU.

She says she subsequently received a call from LSU football coach Ed Orgero who offered to put Guice on the phone to apologize.

Scott told Louisiana state senators that she refused to speak to Guice and urged Orgeron and other athletic officials to keep him out of an upcoming bowl game as discipline - a request that wasn't fulfilled.

After the call, Scott said she never heard from Orgeron again.

The football coach denies ever speaking with Scott.

The testimony came at the second hearing called by female state lawmakers who are following up on an independent report that determined LSU for years mishandled its response to student allegations of rape, domestic violence and assault, in some instances ignoring the claims entirely.

LSU hired law firm Husch Blackwell to review its handling of complaints under federal Title IX laws after reporting by USA Today scrutinized the school´s handling of sexual assault allegations involving Guice and another former football player.

Guice was accused of rape when he was a player at LSU, but university officials never investigated the accusations and Guice was never disciplined, according to the Husch Blackwell report.

Guice was released from the NFL's Washington Football Team in August after his arrest for domestic violence charges.

He has denied all the allegations, including claims of sexual misconduct at LSU, through his attorney.
