A man who was arrested on suspicion of killing his mother and sister in Merseyside has been detained under the Mental Health Act.
Peter Fox, 26, from Bootle, was arrested at London's Euston Station on suspicion of murdering Bernadette Fox, 57, and her 27-year-old daughter Sarah Fox.
The bodies were found at two separate addresses in Bootle between 16 and 17 April. A post-mortem examination revealed the mother died as a result of asphyxiation, while her daughter died from multiple stab wounds.
Police launched an appeal to find Mr Fox after he was found to have travelled to London from Liverpool's Lime Street Station the day before the bodies were discovered.
Police have now confirmed the 26-year-old has been sectioned under the Mental Health Act.
The family spoke of how they are "absolutely devastated" at their loss. They added: "Bernadette, who was a mother of three and grandmother of three, was a very outgoing and lovely person who wouldn't harm anyone. In fact, she only ever had nice things to say about people. She was so caring and would help anyone.
"And Sarah was loved by her family and well-liked by her friends and neighbours. She was a fantastic auntie and was a cheeky, bubbly and outgoing person who loved her dog. They will both be greatly missed."
