TAMPA — The Ye Mystic Krewe pirate accused of pulling down a woman's blouse and stamping her breast during Saturday's Gasparilla Parade of Pirates denied the allegation in a statement sent out Wednesday by his lawyer.

The letter from attorney Paul Sisco includes sworn affidavits from the accused and the man's father denying the allegations and says both passed polygraph exams.

The accusation went viral on Tuesday after the accuser, Rina Alvarez, posted a photo to her Facebook page of the man she said assaulted her. Alvarez also filed a police report, said Tampa police spokesman Steve Hegarty.

Alvarez, 37, told investigators that the pirate was walking the parade route with members of Ye Mystic Krewe of Gasparilla when he approached her as she stood along the railing.

She said the man pulled down her blouse, exposing her right breast, and then used an ink stamp to mark her breast, Hegarty said. She then posted what she believes is a photo of the man who grabbed her to Facebook and identified him.

But the man she identified said it wasn't him and that he's not the man in the photo. He reached out to her on Facebook and denied the allegation.

He then retained Sisco, who said in a statement that his client is the victim of a case of mistaken identity.

"Like all of us, he sympathizes with what happened to the woman who was improperly touched and has offered to help her in any way he could," the attorney said. "However, he can say unequivocally that he was not involved in any way in this incident."

Sisco declined to identify his client or his father, who says he is a corroborating witness for his son.

Both the man and his father swore to the son's innocence in notarized affidavits. Both say the son's costume does not match the costume depicted in the photo. When questioned about the incident during a polygraph exam, Sisco said the son and his father both passed. However, polygraph exams are usually not admissible in court.

Still, Alvarez told the Tampa Bay Times that he is the man who grabbed her. She said she remembers how he walked with a cigar in his mouth, and how his ring scratched her chest when he yanked the top of her dress down to her waist, taking her bra with it.

"I know 100 percent, without a doubt, that that's who did that to me," Alvarez said. "His replies were very coached ... He shouldn't get away with it."

Alvarez provided police with the name and phone number of a friend who witnessed the incident, Hegarty said. She also posted an account of the incident on her Facebook page with a photograph of the man she said groped her. The man is wearing a pirate hat, facial paint and dark sunglasses and appeared to be marching in the parade.

Sisco provided partial screenshots of messages sent between the man and Alvarez after his friends alerted him to the Facebook post identifying him. In the messages, the man denied any wrong doing and said he was misidentified in the photo. He gave Alvarez a phone number and asked her to call him.

"I am not sure what happened to you yesterday, but I never would do that to a woman and I know I didn't yesterday," the man said in a message to Alvarez. "I don't know how the confusion occurred, but I am very sorry if someone invaded you in that manner."

Both father and son confirmed their participation in the parade as members of Ye Mystic Krewe and both confirmed they were dressed as pirates, but said neither "possessed an ink stamp in any way" during Saturday's festivities. In his affidavit, the man's father noted multiple discrepancies with the photo Alvarez posted on Facebook and the costume his son wore that day.

"The gold trim on the person's hat is different, there is no blue buff under the hat nor wig as on the alleged perpetrator, he had pins under the gold on both sides of his hat, the perpetrator did not, and the perpetrator is wearing a wig or has long hair; my son has neither," the affidavit said.

Sisco said he sent the sworn affidavits and the polygraph test results to law enforcement. The attorney could not be reached for comment Wednesday.

In her response to the man's Facebook messages, Alvarez was resolute in her recollection of the incident.

"You pulled my top down. And I had that stamp all over my chest. And scratches from me pulling way," she wrote. "The stamp was underneath my right nipple. I never once pulled my top down, I wasn't drinking. My guy friends couldn't get to me fast enough. He took your pic ..."

Ye Mystic Krewe said it is aware of the allegations and sent out this statement:

"The alleged behavior goes against the values and conduct required by this organization. We take the allegations seriously and pledge all available resources to the investigation. As parents, grandparents and siblings we must do all we can to stand against the type of behavior that has been alleged."
