A 32 year old woman was arrested last night on suspicion of murder and currently remains in police custody. Two men arrested have been eliminated from the enquiry.
A post mortem will begin later today to try and identify how Catherine died.
Detective Chief Inspector Simon Crisp from Avon and Somerset Police said:
"We still need information from members of the public and those people who knew Catherine or knew of her. It is imperative we get a full picture of her life and you may have information that could help."
