Police have arrested a man who reportedly threatened an attack at Ariana Grande's show in Costa Rica over the weekend.

According to Daily Mail, threatening messages were posted on a webpage of the concert organisers and, following a manhunt, a 22-year-old Columbian man with the last names Caicedo Lopez was arrested in his Tibas flat. 

Police reportedly seized two mobile phones believed to have been used to send the threatening messages. 

"The original threat was in the Arabic language and indicated that there could be a situation of danger or an attack at the concert," director of the Judicial Investigation Department (OIJ), Walter Espinoza, said.

"It was a very sensitive situation."

The arrest comes just under two months after a suicide bomber killed 22 people and injured 119 more at Grande's concert at Manchester Arena. 

The pop singer is set to bring her Dangerous Woman world tour to Australia in September; click on theGuide for more details.
