A trawl of An Garda Síochána's disciplinary files has shown there are cases that bear similarities to that of Majella Moynihan, the Garda Commissioner has said.

Ms Moynihan, who featured in an RTÉ documentary earlier this month, was subject to an investigation and threatened with dismissal after she became pregnant by another garda in 1984.

She was 22 years old at the time.

Drew Harris told the Oireachtas Justice Committee that garda records show cases which "bear similarities in respect of unmarried female garda members and it's been recorded on discipline files in respect of pregnancy outside of wedlock".

The commissioner told politicians that Ms Moynihan’s case was a shocking story, a tale from the past that could not happen now.

Mr Harris said he wanted to make it clear that the force was an open and inclusive environment.

He said he had met Ms Moynihan and her solictor last week.

Asked if he supported the payment of an ex-gratia sum to Ms Moynihan and a full pension, rather than the reduced pension she receives after leaving on health grounds, Mr Harris said these matters were subject to negotiations.

He also said he had not been aware of the case before the RTÉ Documentary on One programme was broadcast.
