"The Times newspaper on 10 February 2018 wrote that a current CAFOD employee was named as an Oxfam staff member who had been working in Haiti in 2011, amidst accusations of sexual misconduct", Chris Bean, Director of CAFOD, said in a statement.
Last night the charity's chief executive Mark Goldring sent an open letter to "Oxfam shoppers, supporters and volunteers" in which he "apologised unreservedly" for the scandal.
British actress Minnie Driver has cut ties with Oxfam after 20 years of support.
However, she added that the "abhorrent mistakes of a troubling organization" would not stop her in her charity work.
"Unless you report every serious incident or allegation, no matter how damaging to your reputation - we can not be partners", Britain's International Development Secretary Penny Mordaunt told a conference in Stockholm, according to extracts of her speech released by her ministry.
Mordaunt called allegations about the use of prostitutes by some Oxfam staff in Haiti in 2011 "horrifying".
"No organisation is too big, or our work with them too complex, for me to hesitate to remove funding from them if we can not trust them to put the beneficiaries of aid first", she said. "The case for the type of work done by Oxfam is too strong to allow it to be undermined by bad behaviour", he said.More news: Astronomers Spot Elon Musk's Tesla Flying Through Space After Launch

Just hours after Charity Commission launched an inquiry into Oxfam amid rising sexual abuse allegations, the chairman of the global arm of Oxfam has been held in Guatemala in a corruption probe.
No wonder. According to Oxfam GB's former deputy chief executive Penny Lawrence, the allegations of sexual misconduct were first raised about the Oxfam staff in an earlier mission in Chad.
A senior Oxfam official stepped down Monday after news reports revealed that the humanitarian group had covered up evidence that some of its aid staff hired prostitutes in Chad and Haiti as the organization was delivering disaster assistance to those countries.
He used a slot on BBC Radio 4's Thought for the Day on Tuesday to ask: 'Why have the revelations about staff using prostitutes done Oxfam quite so much damage? But when it is perpetrated by people in positions of power, people we entrust to help and protect, it rightly sickens and disgusts.
Since initial allegations emerged whistleblowers have come forward to allege sex for aid and the abuse of young people in charity shops in Britain.
"It is important that we take this urgent step to ensure that these matters can be dealt with fully and robustly".
Mr MacLeod said charities were not above the law and at the very least they should have reported the crimes to the Haitian police force.
