A man is being questioned in connection with the murder of a woman who was killed while house sitting for friends in West Sussex.
Valerie Graves' body was found at the waterside property in Bosham on the 30th December.
A 22-year-old man was arrested last night on suspicion of murder.
Valerie had been house sitting with her family whilst her friends were away for Christmas.
Police say she had gone to bed at 10pm on Sunday 29th and was found dead by one of her family members at around 10am the next morning, in the bedroom where she had been sleeping.
A post-mortem showed she had suffered significant head and facial injuries, but detectives have not confirmed what weapon had been used.
