More people 'may have been at fire death site'

Officers investigating a fire in which a 14-year-old boy died believe more people than they have identified so far could have been there.
Layton Carr died at the disused Fairfield Industrial Park in the Bill Quay area of Gateshead on Friday.
Police say detectives are now focusing their efforts on identifying all those present at the time of the fire and have appealed for information from witnesses or anyone who knows what took place.
As part of the investigation, 16 children aged between 11 and 14 were arrested on suspicion of manslaughter and released on bail.
Det Ch Insp Mark Atherton urged anyone who was in the area on Friday evening to contact police.
He said: "Regardless of how insignificant you think your information might be, it could really assist our enquiries".
A dedicated online portal has been set up where people can provide information.

Det Ch Insp Atherton said: "A thorough investigation is under way as we determine the circumstances surrounding the tragic incident that night.
"Our thoughts remain with Layton's family and friends as they begin to process the loss of their loved one."
Thirteen boys and three girls have been arrested.
In a tribute, Layton's family described him as a "cheeky, happy lad," with "an absolute heart of gold".
"Layton, we love you more than any words can ever explain. You will be missed more than you'll ever know," his family said.
More than £20,000 has been raised to help his relatives.
Tyne and Wear Fire and Rescue Service said a "severe fire within a section of one of the buildings" at the industrial estate was reported just after 19:50 BST last Friday.
The blaze was brought under control just before midnight.
