Summary
The man arrested by Humberside police is the captain of the Solong cargo ship, the vessel's owner tells the BBC
Earlier, the police force said that a 59-year-old man has been arrested on suspicion of gross negligence manslaughter, following the North Sea collision
Assistant Chief Coastguard John Craig says flames are still visible on the Solong, with salvage plans in place for both vessels
One crew member of the Portuguese cargo ship is "assumed deceased", a UK minister says, as the transport secretary says both Solong and US oil tanker Stena Immaculate are expected to stay afloat
Owners of the cargo ship say it was not carrying sodium cyanide, as previously reported, but had four empty containers that had once held the toxic chemical
