Swimming great Dawn Fraser late Thursday told the Nine Network that she consoled "Junior" Pearce's 17-year-old daughter at a dinner for the Jack Newton Celebrity Golf Classic at Peregian Waters.
She also claimed Gower threatened Pearce's son Mitchell with a bottle at the event where Fraser was also a special guest.
"She was entirely embarrassed and extremely upset about the whole situation.
"I just said `everything will be alright, mum and dad will look after you' and she took confidence out of that.
"Junior ... came and saw me the next morning and he was just absolutely furious.
"Gower chased him (Mitchell) with a bottle and people saw it and just thought `what on earth is happening?'."
The 27-year-old Kangaroos halfback is also accused of damaging a golf car, walking around naked at the Twin Waters resort, being kicked out of an official function and harassing the partner of a high-profile journalist.
The charity event coincided with Gower's week-long buck's celebrations.
He is set to marry long-time girlfriend and Footy Show regular Amanda "Lady Luck" Flynn in three weeks.
Leary is expected to speak to Pearce who is believed to be still on the Sunshine Coast while Panthers chief executive Glenn Matthews is believed to have spoken to Gower on Thursday.
"At the moment I have no comment until I finish the inquiry. I am hoping to do that as quickly as I can," Leary said.
He said the inquiry would take "at least several days to complete".
"Until our investigation is complete there is nothing more I can say," Leary said.
NRL chief executive David Gallop said he was waiting on a "full report" on the Panthers skipper.
"I expect a full investigation from the club and the club has assured us we will get one," Gallop said.
"Clearly there are some serious allegations and if they are proven to be correct then we'd expect the player's club to look seriously ... at some penalties."
Gower was thrown out of the Australian rugby league team for exposing himself to a tourist in 1999 and fined $3000 for breaking a NSW rugby league curfew last year.
But Leary reiterated that Gower was innocent until proven guilty over the recent claims.
"Unfortunately in previous years there have been a few misdemeanours that have occurred," he said.
"But at this stage Craig will be treated as innocent until any allegation is proved against him."
Rugby league great and Gold Classic guest Wally Lewis said he noticed that Gower "had had a drink" at the charity event but believed the halfback's actions may have been blown out of proportion.
"I saw nothing of the things they are talking about," he said.
"I saw him at the dinner and saw that he had had a drink, but so had everybody else.
"I heard the next day that he had crashed a golf cart, and when I asked about it, it was explained to me that he had clipped a rock.
"Of the other things, I was only told about them third or fourth hand - it has surprised and upset a lot of people hearing about it but no one knows if there is any truth in it."
Lewis hoped the allegations did not spell the end of the 27-year-old charity event which raises money for Diabetes Australia and the Jack Newton Golf Foundation.
"It would be a shame if it was ruined by exaggeration," he said.
Tournament host Jack Newton said he was "floored by inconsistencies in media reports" on Gower and labelled it a "witch hunt".
"My biggest disappointment is that the focus of the media attention has been wrongly deferred from the fact that this is a fantastic golf tournament that functions entirely for the benefit of charity," he said.
"It is very disconcerting that a tournament that has run for 27 years and has donated over $2 million to junior golf and Diabetes Australia can be completely overshadowed by a series of unsubstantiated allegations that are based on conjecture."
