The events surrounding the Arctic Sea, a Russian-crewed cargo ship that disappeared for three weeks in July, have become more mysterious.

While Russia maintains the ship was hijacked by suspected pirates and then rescued by the Russian Army, another version of events has added a twist to the tale.

The lawyer for the alleged hijackers has said the men were not pirates, but at sea testing a navigation system on their boat.
