On 5 August, 1969 a bomb exploded at RTÉ Television studios, Montrose in Donnybrook.

In this radio report Tom McCaughren describes what happened and gives details of the damage to the building.

The explosion occurred at exactly 1.30am and could be heard over a wide area of Dublin city. 

It is believed that the explosion may have been caused by a time bomb placed at the rear wall of the studio building. There was no structural damage to the building but there was damage to the large structural plate glass panels which are a feature of the building. No staff were injured by the explosion. 

At this stage Gardaí are investigating what happened but so far there have been no arrests.

It was later discovered that the bomb had been planted by the Ulster Volunteer Force (UVF).
