42 drugs arrests at U2 concert

42 people have been arrested at the U2 concert at Slane Castle this afternoon.

Most of the arrests are for minor drugs offences.

Only one person has been formally charged with possession of drugs.

According to Gardai, however, the crowd is particularly well-behaved this year.

Meanwhile, former Northern Ireland secretary Mo Mowlam is making a return appearance to Slane Castle as a VIP guest.
