On 5 February 1992, there was a mass shooting at the Sean Graham bookmaker's shop on the Lower Ormeau Road in Belfast, Northern Ireland. Members of the Ulster Defence Association (UDA), a loyalist paramilitary group, opened fire on the customers with an assault rifle and handgun, killing five civilians and wounding nine. The shop was in a Catholic and Irish nationalist area, and all of the victims were local Catholics. The UDA claimed responsibility using the cover name "Ulster Freedom Fighters", saying the shooting was retaliation for the Teebane bombing, which had been carried out by the Provisional IRA less than three weeks before. A later investigation by the Police Ombudsman found that the Royal Ulster Constabulary (RUC) had engaged in "collusive behaviour" with UDA informers involved
