Fundraising site GoFundMe has said it has removed a page that was created for a man who was suspected of murdering a Ukrainian refugee on a train in North Carolina state in the US.

Decarlos Brown Jr., aged 34, was charged with stabbing Ukrainian refugee Iryna Zarutska, who escaped the Ukraine-Russia war for protection.

Newsweek, quoting Washington Examiner report, said one page of fundraising for Brown Jr. had been taken down by GoFundMe.

"GoFundMe's Terms of Service explicitly prohibit fundraisers that raise money for the legal defense of anyone formally charged with an alleged violent crime," a statement read as quoted by Newsweek. "Consistent with this long-standing policy, this fundraiser has been removed from the platform and the donors who contributed to the fundraiser have been fully refunded."

23-year-old Ukrainian national Iryna Zarutska was killed in a knife attack while she was travelling on a Charlotte light rail train last month, according to the New York Post.

Zarutska, who had been working at a local pizzeria, was still dressed in her uniform when she stepped onto the Lynx Blue Line at 9:46 pm on August 22.

Footage released by the Charlotte Area Transit System (CATS) shows her quietly scrolling through her phone, unaware of the threat lurking behind her.

Only minutes later, investigators say, 34-year-old Decarlos Brown Jr., a homeless ex-convict, pulled out a folding knife and stabbed her three times, striking her in the neck at least once.

Brown left the train at the next station, where police later recovered a folding knife. He was treated for a hand injury before being booked on a charge of first-degree murder.
