OnlyF model Arikytsya, accused of murdering her boyfriend, has been denied bail…mainly because a court disagreed with her killing him in self-defense.

A judge in Florida will not allow Arikytsya to be released on bail pending trial — her account of how her boyfriend, Christian Obumseli, was fatally stabbed was “not corroborated by the evidence,” according to legal documents obtained by TMZ.

In particular, the judge did not believe Krenney’s claim that she threw the knife at Obumseli from more than 10 feet away… The coroner’s testimony indicated that the wound was too deep and required more pressure than the throwing knife could have exerted.

The judge also ruled there was no reason to release Karenni due to fears she might leave the country… noting that she had enough money to do so if she wanted to.

Arikytsya was charged with second-degree murder in August — four months after the incident — and arrested in Hawaii, CNN reported.
