The 28-year-old's body was found in India on Tuesday
A page set up to help with repatriation and funeral expenses for Irish woman Danielle McLaughlin has exceeded its target in under 24 hours.
A murder investigation has been launched in India after the body of the 28-year-old was found in the state of Goa.
Ms McLaughlin, from Buncrana in Donegal, was said to have left a party on Palolem Beach - a popular tourist resort - on Monday night.
A local man is said to have come across her body the next morning, and reported it to the police.
While a 23-year-old man has been arrested on suspicion of murder, and police say he has confessed.
Police are also investigating if Ms McLaughlin was raped.
Officers made the arrest after obtaining CCTV images showing the suspect with Ms McLaughlin in a number of locations.
A friend of Ms McLaughlin, Christy Duffy, set up a GoFundMe page with a target of €10,000. But it has raised nearly €30,000 in under one day.
Duffy says: "There's not really much anyone can say at the moment as I know we are all completely devastated.
"This fund is to assist the repatriation and funeral expenses for our friend Danielle who was tragically taken from us all too soon this week.
"There is nothing I need to say about Danielle as anyone who knew her, knew that she was a beautiful and kind hearted, funny young lady who loved life and was a loyal and devoted friend, sister and daughter."
And in a statement, her mother Andrea Brannigan said: "The family would like to express our thanks to all who have got in touch since receiving this awful news.
"As you can expect we are finding it very difficult at this trying time.
"We want to thank the Irish and British consulates who, along with Colin from the Kevin Bell Repatriation Trust, and many friends who have assisted at this time.
"Danielle will be sadly missed by us all".
Michael Safi, South Asia correspondent for The Guardian, told Newstalk Breakfast the man arrested is a well known criminal in the local area.
