article: Police are hunting Peter Fox, 26, (pictured) after his mother and sister were found dead half a mile apart in an alleged double murder . A 26-year-old man wanted for the murder of his mother and sister has been arrested after being spotted by a member of the public. Peter Fox, from Liverpool, was arrested at Euston Station in London this morning on suspicion of the murders of Bernadette, 57, and Sarah Fox, 27, following a nationwide manhunt. Detectives released CCTV images of the 26-year-old  leaving Liverpool Lime Street at 8.18pm on Wednesday and arriving at Euston railway station in the capital at 10.57pm. The body of his sister  was found by police on Thursday night, just hours before her 57-year-old mother Bernadette was found dead at sheltered accommodation just half a mile away in Bootle, Merseyside. Merseyside Police said Mrs Fox died of asphyxiation, while her daughter was repeatedly stabbed. Bernadette and Sarah's family today said they are 'absolutely devastated' at their loss. Detective Chief Inspector Dave Rooney from Merseyside Police said: 'I can confirm that a 26-year-old man has been arrested on suspicion of the murders of Bernadette and Sarah Fox this morning and is being brought back to Merseyside. 'A significant amount of work has been carried out over the weekend with the Metropolitan Police and British Transport Police and I would like to thank them for their assistance. 'I would also like to thank the media and the public for their support during the weekend, which has helped us enormously.' In a statement issued through police, a spokesman for the Fox family said: 'We are absolutely devastated following the loss of Bernadette and Sarah and are still trying to come to terms with what has happened to them both. The family of Bernadette (left) and Sarah (right) have said they are 'absolutely devastated' at their loss . '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 aunty and was a cheeky, bubbly and outgoing person who loved her dog. They will both be greatly missed. 'We would ask that people appreciate that this is a sad and tragic time for the family and that we are left alone to grieve in peace, whilst we try to understand what has happened.' The family urged anyone with information about the incident to contact police to help them 'find justice for Bernadette and Sarah'. Sarah Fox's body was found around 9pm on Thursday night after police received a phone call about her welfare. A neighbour had reportedly raised the alarm after seeing a dog loose on the streets. Detectives released CCTV images of Peter Fox arriving at Euston Station (right) in the capital at around 10.57pm on Wednesday night after leaving Liverpool Lime Street at 8.18pm (left) Another neighbour living close to the flat, who did not want to be named, said: 'I saw one of my neighbours in the street who said he was worried after he noticed the dog from the flat roaming the streets, he had seen it a few times so he knocked on the door but got no answer. 'He called to the house last night and noticed there was a downstairs window open and the back door was ajar.' It was then that the police were called and officers found Sarah Fox's body, who they said had suffered 'multiple injuries'. 'It's so shocking. I've spoken to the girl from those flats before two or three times, she seemed a nice girl,' the neighbour added. Bernadette Fox was found when police arrived at her address through other enquiries. One neighbour near the sheltered housing property, who did wish to be named, said: 'The girl's name was Sarah - people called her Foxy - and her mum was Bernie. Police launched a double murder inquiry after the bodies of two women were found at separate addresses in Bootle, Merseyside. Pictured, officers outside a property in Worcester Road . Sarah Fox, 27, was found dead with multiple injuries at around 9pm on Thursday evening, after police were called to Worcester Road (pictured) over concerns for her welfare . 'Bernie was harmless and Sarah I think had worked at a solicitors nearby, Bernie had a son as well. 'The place where Bernie lived was sheltered accommodation and it had cameras all over the place. 'There's a camera over the intercom so anyone letting someone in would see them. It's a hard place to get into.' Martin Stevenson, Director of Older People's Services at Your Housing Group, said yesterday: 'Tragically a body was discovered at one of our Roger Arden Court sheltered scheme apartments in Bootle this morning. 'Merseyside Police attended the incident and we are continuing to support them with their investigations. 'Our thoughts are very much with the family and friends of the deceased at this difficult time.' Patricia Doragh, who lives in a property near the flat, said: 'It is quite a rough area around here especially up the side streets. 'The police are always up and down the main road it's not a rare thing, it's a street quite well known for alcohol. 'When I took my grandsons out earlier about 12 o'clock there was nothing here and now all the cordons are up.' Sorry we are not currently accepting comments on this article.
