Sinn Féin has put on display another bug it says was discovered at one of its offices in west Belfast.
According to the party, the listening device was found in a floor at Connolly House in Andersonstown on Monday night.
Last week, Sinn Féin put on display another bug which it said had been found at the Belfast home of a woman who works for the party president Gerry Adams.
It comes as the North's political parties finalise their positions for this week's intensive political talks at Leeds Castle in Kent, aimed at restoring devolution.
