Police probing the cause of the fire at the Penhallow Hotel in Newquay last summer, where three people died, have arrested the hotel manager and his wife.
Andy Woolam, 42, was held overnight for questioning at Newquay police station while his wife Sarah, 36, was bailed.
Neither has been charged.
The blaze was rated one of the worst hotel fires in recent history with one man jumping to his death from a third floor window.
A 44-year-old man and a 21-year-old man were arrested and bailed earlier this year but so far no charges have been brought in the case.
The case attracted national headlines and in February Crimewatch aired an appeal to encourage new witnesses to come forward.
