Scientists investigating the mass pollution which injured and killed hundreds of sea birds along the south coast say the source of the contamination may never be known.

Around 300 birds, mostly guillemots, were treated at the RSPCA West Hatch centre near Taunton following the spill. The Maritime and Coastguard Agency said that it had been unable to trace the source of the spill and confirmed it has closed the investigation.
