Security tightens at Doonbeg as Lowry leads Irish Open charge

Various military vehicles snaked around the property on Friday ahead of Marine One’s arrival. Players are conscious that play may have to be temporarily halted for the helicopter’s arrival.

As Shane Lowry recovered from his only wobble of a superb second day, the beach behind him was being combed by a slow-moving line of security personnel conducting a thorough search operation.

Lowry stood on the 14th green having bogeyed the previous hole. It is a stunning par-3, playing downhill back towards the clubhouse with a sweeping view of the Atlantic all along the right.
