A fundraising page for a victim of the terror attack in Westminster has been taken over by JustGiving, amid concerns it was set up by a fraudster.
Concerns were raised after donations began to be made to raise money for the family of Aysha Frade.
Users who searched for Elisia Evetts - the name listed as the administrator for the page - found someone with the same name had been convicted of fraud in 2013.
JustGiving, which has been criticised for taking a 5% fee from each donation, also found the username had been changed a number of times since it was first set up.
By Saturday morning, the page had raised more than £15,000 for Ms Frade's family.
The 43-year-old was killed when Khalid Masood drove a 4x4 vehicle into crowds of pedestrians on Westminster Bridge on Wednesday.
Multiple fundraising pages have been set up to help the loved ones of PC Keith Palmer, who died after being stabbed in the grounds of the Palace of Westminster.
An official Metropolitan Police Federation memorial page, launched on Thursday, had raised nearly £700,000 on Saturday.
The association set up the page after receiving a huge number of pleas from members who wanted to help, chairman Ken Marsh said.
He added: "This gives a clear indication of what the public thinks of my colleagues. I'm not surprised at all.
"I've been told to leave it open because it's for people to show their respects, and how they want to do it. It's just amazing - amazing - the generosity of individuals."
More than $63,000 (£51,000) have been donated to help the injured partner of Kurt Cochran, a US tourist who also died on the bridge.
Relatives said his wife Melissa had suffered a broken leg, a broken rib and a cut to her head, but would recover from her injuries.
