The accident happened on Friday while the diver was underwater in Porticello, police said, adding the precise cause of death was still unknown. According to local Italian media, the diver was a 39-year-old Dutch national who worked for a specialist salvage company. It comes as salvage ships arrived earlier this month to waters off the small port of Porticello, near Palermo, where the Bayesian vessel sank during freak weather last August. Seven of the 22 people onboard the Bayesian last summer were killed, including Mr Lynch, 59, and his 18-year-old daughter Hannah.
