A 23-year-old man is being held in custody by police after his mother and sister were found dead at their home in Cumbria.
The man was arrested by police on Saturday morning after neighbours reported hearing people shouting. Armed police surrounded the terraced house at the address in Millom, Cumbria, at around 8.30am.
The victims were identified as Alice McMeekin, 58, and her daughter Katie Jenkin, 20. Both were both found dead at the scene.
Cumbria Police said they have launched a murder inquiry. They said they have arrested a man on suspicion of murder and were not looking for anyone else in connection with the crime.
The force issued a statement, saying: "An investigation has been launched and a man, aged 23 from Millom, was arrested near by on suspicion of murder and remains in police custody."
Detective Chief Inspector Paul Duhig, who is leading the investigation, said: "A team of detectives are working on this investigation to establish the circumstances surrounding these tragic deaths.
"Events such as these are rare in Cumbria and we are doing everything we can to ensure that the victims' families are supported and the offender is brought to justice."
