Garda Commissioner Drew Harris and Junior Justice Minister James Browne will unveil a monument in Ballinamore today to honour two men killed during the Don Tidey kidnap.
Private Patrick Kelly and Garda recruit Gary Sheehan were shot dead by the IRA in 1983, during the rescue of the Quinnsworth boss in Derrada Wood.
The monument will be unveiled at Ballinamore Garda Station, after a remembrance ceremony in St Patrick's Church nearby at 11.30am.
Leitrim cathaoirleach Paddy O'Rourke is welcoming the event.
