Gardai have released a man without charge after he was questioned over the deaths of two young men in Cork last weekend.

He was the fourth person to have been detained following the deaths of Michael Coleman and Liam Coffey. Three others have also been released.

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

The case prompted the HSE to warn recreational drug users in the area not to take it.
