A man in his late twenties is still being questioned by gardaí in Bandon in connection with the deaths of two young men in Cork at the weekend.

He’s the fourth person to have been arrested following the deaths of friends Michael Coleman and Liam Coffey – three others have been released.

Gardaí believe the men may have consumed a powder containing ecstasy, which could have led to their deaths.

It’s prompted a warning from the HSE, urging any recreational drug users in the Cork area not to take a brown, powdery substance.
