Model Lauren Mochen has come out and accused boyfriend and NHL player Arthur Kaliyev of defrauding her out of tens of thousands of dollars to fund what she claimed was a rampant gambling addiction that also severely affected his teammates.
In a New York Post article that reviewed messages, receipts, accounts and even an incident report, Mochen said Kaliyev defrauded her of $50,000 during their three-year relationship. The model claimed on social media that Kaliyev used intimidation tactics – telling her people would hurt him unless he paid – suggesting indirect ways to funnel his money through her accounts and reimbursing her with fraudulent checks.
That ordeal allegedly started in 2023, when Kaliyev told his then-21-year-old girlfriend that he had received a check from his family to reimburse her for “accidentally” using her PayPal account to pay workers at his family’s shipping company.
Mochen had previously accepted Kaliyev’s proposal to link his card to her PayPal account and transfer money through it after he claimed his personal account was experiencing problems, according to her social media posts.

The $400 check was allegedly deposited into the cellphone, but Kaliyev soon told Mochen that his personal bank account had been frozen due to his family’s financial transactions and that he needed the money back.
He then asked her to repeat the process with additional checks from his family’s company, deposit them into her account and send the money to him digitally, according to the Post. Over the course of about a week, she told the outlet she handled several checks totaling $7,500.
Mochen then sent the money back via Apple Cash, hoping he would refund her the full amount once his account was freed, the outlet said. But when she checked her bank account after several days, she was shocked to find a reported negative balance of $7,000.

The bank said, ‘You cashed three fraudulent checks, who did these come from? Why did you do that?'” Mochen recalled to The Post.
According to the report, the bank told Mochel that each of the checks bounced, but she had already paid Kaliyev $7,500 of her own money, on top of what he already owed her.
Mochen emphasized that while she transferred large sums of money to Kaliyev, he repeatedly claimed that people wanted to harm him and that he would pay her back, according to her social media posts.

Mochen added that she had noticed other financial behavior from Kaliyev, the Post said. When he started discussing money with her, he switched to Snapchat, where messages disappear after 24 hours. Meanwhile, Mochen said Kaliyev allegedly used her personal information and a different phone number to set up a separate PayPal account, leading to the theft of an undisclosed additional amount that was not included in the $14,114.88 she claims he took through his original account.
After her problems with Kaliyev’s checks and her bank — and after their breakup — Mochen filed an incident report on Sept. 4 at her hometown police station in Saginaw Township, Michigan, to begin contesting the charges with her bank related to Kaliyev’s alleged fraud.
Mochen is not the only one affected by Kaliyev’s alleged disturbing money habits, the New York Post reported.

Mochen told the station she heard Kaliyev owed several Kings players about $50,000 for a collection of fines, fees, group bets and betting pools, citing a text message involving current SKA St. Petersburg wing Igor Larionov II and longtime Kings defenseman Drew Doughty.
Another current Kings player confirmed to Mochen over Snapchat that Kaliyev still owes money to players on the team, the Post reported.

A source also told the station that Kaliyev owed money to coaches and his trade would be delayed until he settled that debt.
Mochen claimed, and text messages from Kaliyev appear to confirm to the Post, that Kaliyev was even barred from the practice regarding the unpaid debt.
