Report to state that Flynn issued numerous denials of knowledge of claims to the 'ICHH' board
The report will state Flynn issued eight separate denials of knowledge of the claims to the ICHH board in the week leading up to his suspension from the charity on August 7.
He had been quizzed by gardaí in relation to allegations made by two separate men last May.
A third complainant alleging sexual assault against Mr Flynn, who died by suicide on August 18, made a formal statement to gardaí at Store Street Garda Station on Thursday of last week.
The report is due to be submitted by former and present board members to the charity's members at an Emergency General Meeting of the ICHH tomorrow evening at 7pm.
A source told the Sunday World "the report will be a factual and sequential outline of the events and actions taken by the board over a four-week-period dating from July 30 to August 26."
The narrative section of the report is expected to run to 12 pages while attachments, including text messages exchanged between the former chair of the board David Hall and the now deceased councillor Mr Flynn, will run to an additional 38 pages of documents.
The report is also expected to detail media inquiries the board received in relation to the allegations against Flynn - and the response issued by the charity.
A source said: "A narrative has been spread in the north inner city that Anthony Flynn was thrown under the bus by the board of ICHH.
"The report will detail communications that show this was not the case and also clear up any misconception that Anthony Flynn was suspended because of the allegations against him.
"The report will clearly detail the events leading up to Anthony Flynn's suspension, the efforts by the board to encourage staff and volunteers to engage with and support Anthony, and detail the communications that took place between him, the board and it's chair David Hall."
The original two complainants against Flynn went to gardaí in May alleging they had been sexually assaulted at his home after he ordered taxis for them bringing them to the property.
Mr Flynn was interviewed by gardaí about the allegations.
However, when the charities regulator wrote to the board of ICHH in late June, querying an allegation that a worker with the organisation had behaved in a sexually inappropriate manner, Flynn did not divulge the allegations made against him to his fellow board members.
The Board responded to the charities regulator, basing its response on the denials from Flynn, stating it was unaware of any allegations.
Shortly after, gardaí contacted ICHH requesting the charity's taxi receipts from the period during which the assaults took place.
It was at this point that the board learned Mr Flynn was under investigation in relation to the sexual assault allegations.
He was subsequently suspended from ICHH on the grounds he had misled the board.
Subsequently, ICHH received queries from two separate media organisations in relation to allegations a staff member was under investigation for sexual assault.
The board's chair David Hall responded to these queries confirming that a staff member had been suspended but no details were given in the statement that could have led to the identification of Anthony Flynn.
The statement confirmed that an employee had been suspended, following "serious matters" that came "to the attention of the board".
Six days later, Mr Flynn died by suicide.
His death caused widespread shock and anger in the inner city where he was a popular character and revered for his work in helping the homeless.
Mr Hall subsequently stepped down as chair of the charity citing threats to his safety,
In a note to the charity's staff confirming his decision to step down, Mr. Hall said the days after Mr Flynn's death had seen an "unwarranted social media blame campaign", which had led to "personal safety threats against me and others."
