Two people are feared to have died after two cargo ships collided in the Baltic Sea off the Swedish coast early on Monday, causing one to overturn. Prosecutors have begun an inquiry into alleged gross negligence at sea involving the UK-flagged Scot Carrier. The coastguard was also investigating suspected drunkenness on board. Rescue boats and helicopters have so far failed to locate the pair who were on board the capsized boat, the Danish-registered Karin Hoej. A spokesman for the Swedish Maritime Administration (SMA) said screams had been heard from the water after the collision in the early hours of Monday.  “It is very cold and dark,” Jonas Franzen told the BBC. “The water is about 4C (39F) and the air is about 5C (41F).” The incident occurred in an area of the Baltic Sea between the southern Swedish coastal town of Ystad and the Danish island of Bornholm, he said. Johan Nilsson, in charge of the rescue operation, told Swedish media the hull of the Swedish boat had signs of being completely run over.(BBC)…[+]
