Police believe Mrs Charlton's property had been burgled
Detectives investigating the murder of an 85-year-old woman at her home in Hull have arrested a man.
Joan Charlton died from head injuries as a result of a "sustained and brutal attack", in which every bone in her face was broken, police said.
Her body was found at her home on West Parade on Thursday afternoon after a call from a member of the public. It is not known how long she had been dead.
Police said the 20-year-old man, from Hull, was being held in custody.
Earlier police said they wanted to trace a man in his 40s who had tended her garden.
Senior investigating officer Det Supt Dena Fleming said: "Joan died from a sustained and brutal attack.
"She's died from head injuries but every bone in her face has been fractured.
"This was a violent attack of an elderly lady in her own home, where you would expect to feel safe and be safe."
