The owner of a caravan site where 50 caravans were destroyed by fire says there were floating lanterns let off into the sky on the night the blaze took hold.
The caravans were being stored at the Croft Farm Waterpark, where there is also a boating lake.
The owner said there was a party in the site's clubhouse, and chinese style floating lanterns were set off into the sky.
A spokesman for the Hereford & Worcester Fire Service said it was too early to say how the fire started. He did not rule out the possibility it could have been caused by a floating lantern.
