The bow of the cruiseferry struck one of the Gantry cranes causing it to catastrophically collapse onto the quay below as she was manoeuvring.
At 16.20 local time, the "man overboard" alarm was sounded on board the ferry and the engines were stopped.
A MOB was launched and resque services from Sweden, Germany and Poland participated in the search.
Surveillance tapes from the ferry and interviews with witnessed determined that the cause was a deliberate jump overboard by the mother of the 7-year-old boy.
