Convicted fraudster Catriona Carey is said to have transferred thousands of euro to her brother DJ Carey from a business account which is currently under Garda investigation.
The Sunday Independent reports that two payments were made from Careysfort Asset Estates to an account in the name of the former hurler in 2020.
Ms Carey has been convicted of tax offences in 2008 and of theft and fraud in 2020, receiving an eight-month suspended sentence.
Some €2,000 was transferred from Careysfort to an account called 'DJ Carey' and another €2,000 was transferred to an account called 'DJ Carey AIB'.
Mr Carey, a well-known figure in the GAA world, secured a settlement with AIB Bank in 2017 that saw his over €9.5 million debt reduced to just €60,000.
This meant that he only had to pay back 0.63% of the debt which consisted mainly of loans he took out for his properties.
The 51-year-old former Kilkenny hurler achieved the 'compromise' that also included a 'windfall' clause that means any cash or assets that cause an increase of €50,000 in his net asset value would have to be paid to AIB.
Ms Carey, a former Ireland hockey star, was arrested last week and was questioned for 12 hours about her role as director of Careysfort.
She was released without charge.
This is separate to the investigation into allegations that she received money from mortgage holders to do deals on distressed loans and kept the money without the promised arrangements being struck with lenders.
