The woman arrested for running off with a pro boxer’s bling-filled bag claims she’s no bag snatcher — she was told to abscond with the pricey pack when a fight broke out.

“She’s the one holding the bag and that’s why she got arrested. This could happen to anyone,” accused thief Sarah Morin’s lawyer, Gerard Marrone, said at her arraignment in Manhattan Criminal Court Tuesday.

The buxom blonde is accused of fleeing from Jay Z’s 40/40 nightclub Sunday morning with fighter Jermall Charlo’s blue Louis Vuitton bag — plus $150,000 in cash and jewelry that was inside.

Morin, a nurse, was celebrating her 40th birthday at the club with her gal pals when Charlo invited them upstairs to the club’s VIP lounge, according to Marrone.

A few hours later, the light middleweight boxer got into a fight with another patron — and his body guard thrust the bag into Morin’s hands and instructed her to hightail it out of there amid the melee, he said.

Within an hour, she’d already called the guard and said she wanted to give the bag back — and they continued texting through the next day to arrange a hand-off, Marrone claims.

“They texted back and forth. She said, ‘I live in Connecticut.’ He said, ‘Go home to Connecticut, I’ll have someone pick it up,’” Marrone said.

“The next thing she knows, a day later she gets call from detective saying, ‘Come in to the precinct.'”

Morin turned herself in Tuesday — along with the bag and jewelry, which she says included chains, medallions and a diamond-encrusted boxing glove charm.

The police report says the bag also contained $40,000 in cash — the criminal complaint says $25,000 — but Marrone claims there was no money in there at all.

“Who goes out with $125,000 worth of family jewels to a nightclub? It’s ridiculous. Get a safe,” he said.

Cops, however, say they’re still looking for the money.

“We recovered the jewelry and the whereabouts of the $40,000 remains under investigation,” a police spokesman said Tuesday.

Charlo, meanwhile, has declared the entire story “fake news.”

“Fake News YEA F–KING RIGHT,” he tweeted Sunday alongside a link to a news report on the bag heist.

Morin was released on her own recognizance and is due back in court April 17.
