Italian prosecutors have placed under investigation the captain of the superyacht that sank off Sicily last week in a storm, killing British tech magnate Mike Lynch and six other people, a judicial source said on Monday.
 
James Cutfield, a 51-year old New Zealand national, is being investigated for manslaughter and shipwreck, the source said, confirming earlier reports by Italian media.
 
Being placed under investigation in Italy does not imply guilt and does not mean formal charges will necessarily follow. Notices to people under investigation need to be sent out before authorities can carry out the autopsies on the bodies of the dead.
 
The decision was made after Cutfield was interrogated for a second time. Reuters has been unable to contact Cutfield.

 
It is still unclear whether other members of the crew or other people will also be put under investigation along with the captain.

Six killed in shipwreck

The British-flagged Bayesian, a 56-metre-long yacht, was carrying 22 people when it capsized and sank on Monday within minutes of being hit by a pre-dawn storm while anchored off northern Sicily.
 
Fifteen people survived, including Lynch's wife, whose company owned the Bayesian. Lynch's 18-year-old daughter, Hannah, was among the victims.
 
While the yacht had been hit by a sudden meteorological event, it was plausible that crimes of multiple manslaughter and causing a shipwreck through negligence had been committed, the head of the public prosecutor's office of Termini Imerese, Ambrogio Cartosio, said on Saturday.

An investigation is underway to determine why a superyacht sank off the coast of Sicily, killing seven on board. Lauren Bird breaks down expert analysis about the speed at which it sank and explores whether more could have been done to prevent it.
 
Maritime law gives a captain full responsibility for the ship, crew and all on board.

Cutfield and his eight surviving crew members have made no public comment yet on the disaster.
 
"The Bayesian was built to go to sea in any weather," Franco Romani, a nautical architect who was part of its design team, told daily La Stampa in an interview published on Monday.
 
He said the yacht could have taken on water from a side hatch that was left open.
