Banned from Bangladesh and India, a storage tanker branded as toxic has ended its final voyage on the shipbreaker's beach at Gadani in Pakistan.

The arrival of the 60,500-dwt Radiant (built 1983) has incurred the wrath of government ministries in Islamabad who want to know how it happened when they had expressly forbidden the vessel's entry into Pakistan.

A high-level investigation has been launched into how approvals are granted by local authorities, and how a vessel that NGO Shipbreaking Platform had claimed to have 1,500 tonnes of slop oil and sludge with mercury levels of 395 mg per kg was allowed to be beached.
