The Garda Commissioner has said the investigation into allegations of sexual assault against the late CEO of the Inner City Helping Homeless charity, Anthony Flynn, is continuing.

Drew Harris also said that in light of the allegations gardaí may have to review their decision not to vet all of those working in homeless services.

Mr Harris said there are strict criteria for garda vetting, but that as homeless people could be regarded as vulnerable, it may be an area that needs resolution.

Minister for Justice Heather Humphreys said the Department of Justice is completing a review of vetting legislation, and she said the department would be happy to make changes in this area if its found to be necessary.

A document sent to members of Inner City Helping Homeless, a Dublin-based charity, detailed four serious allegations of abuse that were made against the former CEO, who died in August.

Written by David Hall, the former chairman of the charity, the document outlined a series of allegations of sexual abuse that were being investigated by gardaí earlier this year.
