Russian shipowner Fesco has seen its stock price hammered after the arrest of one of its main shareholders.

Summa Group co-owner Ziyavudin Magomedov, 49, was arrested over the weekend in Russia on charges of embezzling more than $35m, Reuters reported.

Magomedov denied the charges at a pre-trial hearing, where a judge ordered that he be held in custody until 30 May.
