Hoegh Autoliners said in a statement seen on Sunday that, after a delay of more than a week, no crew have been arrested. No illegal drugs were found, it added.

The ship, which carried UN vehicles, arrived at the Kenyan port of Mombasa on September 17 and was boarded by Kenyan authorities who suspected it was carrying illegal weapons and drugs.

After Kenyan authorities revealed they had found undeclared weapons aboard the ship, the UN said the weapons found were part of declared cargo packed in India and destined for the Indian battalion in the UN peacekeeping mission in Congo.
