Two executives of Croatian shipowner Uljanik Plovidba have quit following their arrests in relation to a probe into "financial damage" at unrelated shipbuilder Uljanik Group.

The tanker and bulker owner said its director Dragutin Pavletic had tendered his resignation, while Anton Brajkovic, deputy president of the supervisory board, later did the same.

No mention of the shipyard investigation was made in the statement by Uljanik Plovidba.
