Unknown substance drifting off Sweden

·1-min read

An unknown substance is floating in the sea between Sweden and Finland, covering 77 square kilometres, the Swedish coastguard says.

While the nature of the substance is unclear, the coastguard has ruled out an oil breach.

There is currently no danger of the substance reaching land, officials said.

The substance - first spotted on Wednesday in the northern part of the Baltic Sea - was no longer visible by Thursday but that did not mean that investigations into a possible environmental crime would be dropped, the Swedish coast guard said.

Those looking into the incident were scrutinising what ships had been in the area with what cargo on board.

A laboratory analysis will provide information about the substance next week at the earliest.

It could possibly be biofuel.

Images showed a long, thin layer floating on the surface of the water, extending into the Swedish and Finnish economic zones.
