Stena Bulk has revealed one of its MR tankers has scared off a potential pirate attack in the Red Sea.

The 50,000-dwt Stena Imperial (built 2015) was west of Yemen on 3 November when the suspected gunmen approached in two skiffs.

They came towards the port side at a distance of 1.5 nautical miles.

The alarm was raised and the master and security team mustered on the bridge.
