A NEWPORT supermarket's petrol station remains closed today while investigations continue into an incident of suspected contamination that led to problems for a number of motorists.

Asda said that it hopes to be able to reopen the petrol station at its store at Lower Dock Street in Pill by "tomorrow at the latest".

Four vehicles broke down at Monday evening near the junction of John Street, after filling up at the petrol station.

Gwent Police assisted the occupants while they awaited breakdown assistance.
