Three men who collapsed after taking a "suspected overdose" in Belfast city centre at the weekend have now left hospital.

All three were found unconscious on Saturday night just before 21:00 GMT on Donegall Pass.

One of them was later described as being critically ill.

They were treated at the scene before being taken to hospital. PSNI said on social media that the men collapsed after a "suspected overdose".

Police said they assisted paramedics providing emergency first aid to the three men.

"This clearly could have had dire consequences for those involved," they said.

The man described as critical was taken to the Royal Victoria Hospital's intensive care unit.

On Monday, a spokesperson for Belfast Trust confirmed that all three had now been discharged from hospital.
