Police have arrested a man on suspicion of planning a terror attack at an Ariana Grande concert in Costa Rica.
Detectives launched a manhunt on Saturday after threatening messages were posted in Arabic on a webpage of the concert organisers.
Officers seized two mobile phones allegedly used to make the threats.
On May 22 a suicide bomber killed 22 people and injured 119 more at a concert by the American singer in Manchester, and Costa Rican police feared a copycat attack was being planned.
After being arrested he was handed over to state prosecutors.
Ariana Grande, 23, later performed for 14,000 fans as planned at the Parque Viva.
Organisers said in a statement: 'The operation was carried out with total professionalism.'
On Saturday police carried out an emergency drill to check security arrangements at the park ahead of the concert.
All fans were searched as they passed through three rings of security.[DailyMail]
