Blood-soaked teen girl danced nude on broken glass after taking '2CB'
A teenage girl showed "no pain" as she danced naked around a bedroom with shards of glass on the floor in the Cork house where the designer drug 2CB was taken.
She was covered in so much blood, it was "impossible to tell" if she had any wounds to her body.
And she was "so out of it", she failed to recognise that a young man was lying on the floor having suffered a suspected heart attack, a witness revealed.
An 18-year-old man is in a critical condition and three others remain in hospital after taking the drug 2CB. The dangerous ecstasy substitute was consumed at a house party in the Greenmount area of the city.
Gerard Banks, who was first at the scene, explained how he was walking home when he heard "crazy shouting" coming from inside the house.
He said: "When we got into the house, there was blood everywhere.
"We just didn't know what we had stumbled upon.
"Those in the house were not in control of themselves. Some were injured and soaked in blood from head to toe."
Gardaí at Anglesea Station in Cork are investigating the matter. They believe students had been socialising in the city before returning to the house late on Monday night.
A man has been arrested in Cork and was being questioned about supplying drugs.
The 29-year-old was being held at Bridewell Garda Station after a number of raids in the city on Tuesday night.
Three other men were also arrested, but were released without charge.
Gardaí carried out raids at two addresses and discovered traces of the 2CB drug.
Drugs Minister Aodhdan O Riordain admitted that synthetic drugs such as 2CB are being continually re-packaged and that authorities are playing "catch-up".
