Gardaí have released without charge two men arrested for questioning about reported sexual assaults on two teenage girls following a concert in Cork.

A file is to be prepared for the Director of Public Prosecutions.

The two teenagers, aged 18 and 19, went to the Savoy nightclub in the city after the concert by American singer, Jason Derulo at the Live in the Marquee venue on the Marina near Blackrock.

It’s believed that the two girls met a number of Mr Derulo’s entourage at the nightclub and they were invited back by the group to the singer’s tour bus which was parked in the city centre.

The two teenagers, who are from Co Cork, contacted gardaí at Anglesea Street sometime before 4am to report that they had been sexually assaulted on board the tour bus.

Gardaí arrested two American men in their 30s and 40s in the Grand Parade area shortly afterwards and brought them to the Bridewell Garda station for questioning about the reported sex assaults.

Both men were held under Section 4 of the Criminal Justice Act which allows gardaí detain suspects for up to 24 hours before they are either released or charged.

The two were released shortly before 9pm.

Gardaí also released Mr Derulo’s tour bus which had been impounded to allow garda technical experts carry out a forensic examination of the bus following the complaints.

The two girls were taken by gardaí to the sexual assault unit at the South Infirmary Victoria University Hospital where they were medically examined by doctors early on Friday morning.

Miami born Mr Derulo (24), who is due to play a concert in Ipswich tomorrow night as part of his Tattoos world tour, was not on the tour bus at the time of the reported sexual assaults.
