Former boxing champion Vinny Paz allegedly punched another man “in the face multiple times’’ late Monday in Providence, leaving the victim with an eye swollen shut and several broken teeth, according to police reports.

The details were included in Providence police reports laying out the allegations against the 55-year-old Paz, who adamantly denies the charges and claims the alleged victim, Nathaniel Lavoie, 34, had earlier ransacked his Warwick home and stolen $16,000.

Paz was arraigned Wednesday in a Providence courtroom on a felony assault charge and freed on $5,000 bond. He was also ordered to stay away from Lavoie, WPRI-TV reported.

According to a police narrative, a woman named Mindy Baptista told officers she heard loud banging at the door to her Hawkins Street apartment around 11:30 p.m. Paz “rushed in’’ with his girlfriend when Baptista opened the door, and he confronted Lavoie with theft allegations, the narrative said.

The argument got physical, according to the report, and Lavoie later told police that Paz “punched him in the face multiple times causing him to lose/break several teeth.’’

Officers observed “Lavoie’s left eye to be black-and-blue with heavy swelling,’’ and he claimed he had been bitten several times on his left hand and bicep, the report said.

Paz and his girlfriend, Alexis Kooger, fled in a black Jeep Cherokee with temporary plates after Baptista informed them that she had called police, according to the document.

In addition, Baptista said Lavoie briefly lost consciousness and fell at least three times after the alleged assault. A detective later noted that Lavoie’s left eye was “swollen shut’’ when he was admitted to Rhode Island Hospital, and a bottom front tooth was missing.

Another witness, Jonathan Santos Castro, told police he was sleeping in Baptista’s apartment when all the commotion woke him up. He said he also saw Paz hitting Lavoie with a closed fist, and that Paz “appeared intoxicated, angry, and was accusing Lavoie’’ of pilfering $16,000 from the fighter’s bedroom in Warwick, the report said.

Paz, a five-time boxing champion whose stunning comeback from a broken neck was chronicled in the 2016 film “Bleed For This,’’ has angrily denied the accusations on social media, as has his business associate, Zena Sciarrino.

“Tried to help someone and I’m now the bad guy!!’’ a defiant Paz tweeted Tuesday. “Rap sheet I get robbed and I’m the victim and the media wants to side with liar thief!! Ok use to it.’’

Sciarrino told the Globe in a recent e-mail, “This guy [Lavoie] has a rap sheet! Go look. Next Vinny filed a report on his home robbery! Detectives on the case! Next he didn’t break in anywhere! He has a broken nose! This kid he tried to help. Many times! . . . Vinny is the victim!’’

Both Paz and Lavoie have had prior brushes with the law.

Lavoie’s criminal history includes no contest pleas for driving with a suspended license; a 2013 domestic assault charge that was dismissed; no contest pleas in 2014 for felony domestic assault, simple assault, and domestic vandalism; fugitive from justice charges that were dismissed; a 2010 simple assault charge resulting in a no contest plea; and a no contest plea that same year to drunk driving, according to court records.

Paz has been in similar jams.

He pleaded no contest in 2012 to a charge of disorderly conduct, and a simple assault charge in that case was dismissed, records show.

He also pleaded no contest in July 2007 to a charge of drunken driving.

Two years earlier, the champ was booked for resisting arrest but had that charge dismissed as well. An impaired driving charge stemming from an incident in 2000 was also dropped, according to court records.

Long before his legal entanglements, Paz carried the hopes of many Rhode Islanders on his shoulders during a decorated pugilistic career that spanned 1983 to 2004. He retired with a 50-10 record that included 30 knockout victories.

The flamboyant Cranston native plied his trade under the nickname Pazmanian Devil and was a two-time champion when he broke his neck in a car crash in 1991.

Despite being told by doctors that he would never fight again, the gritty boxer came roaring back within a year, returning to the ring and going on to capture three more titles.

Among his notable victories during the comeback were two wins against an aging Roberto Duran, a feared puncher whose nom de guerre, “Manos de Piedra,’’ translates to Hands of Stone.

Duran was portrayed in “Bleed For This’’ by Worcester light heavyweight contender Edwin “La Bomba’’ Rodriguez. Paz was played by Hollywood star Miles Teller in a performance that earned critical raves.

The next round in the boxer’s pending legal drama is slated for April 5, when Paz is due in court for a prearraignment conference.
