Italian shipowner Raffaele Brullo has been released from house arrest in a continuing probe into a fatal tanker collision last year.

The principal of Augusta Due was freed on 4 March by an appeals court in Palermo, a company statement said.

The decision revoked an arrest order by the investigating judge in the case over an incident involving a ship suspected to be Augusta Due's 11,300-dwt Vulcanello M (built 2006) and a fishing boat that killed the three men on the smaller vessel.
