DOZENS of residents were evacuated and rushed to hospital after mysteriously falling ill in a suspected gas incident at a block of flats.
Around 60 people were rescued after firefighters were scrambled to the scene in Butetown, Cardiff, at around 10.18pm yesterday.
South Wales Fire and Rescue Service said a number of residents had reported feeling unwell with symptoms similar to carbon monoxide poisoning.
They were rushed to the University Hospital of Wales for further tests.
Four fire engines were called out alongside several specialist officers and appliances.

The fire service confirmed all residents have since been allowed to return to their properties.
