Specially-trained police are preparing to speak to a 94-year-old grandmother who was attacked while she was asleep in her bed at home.
Emma Winnall, from Moseley in Birmingham, was assaulted after going to sleep on April 30, in an attack which left her with a fractured skull, a broken arm and wrist, a partially-severed finger and other injuries.
The grandmother-of-seven remains in hospital having undergone emergency surgery, including having metal plates inserted into her arm.

Detectives have so far been unable to determine a motive for the attack - and it is not thought anything was stolen.
Police remain in the area to reassure locals and also to appeal for help in tracking down the attacker.
The photograph of Mrs Winnall - who worked during World War II in an armaments factory - in hospital was released at the request of her daughter as part of the police appeal.
Detective Chief Inspector Sarb Johal said police believed "an implement of some sort" was used in the attack.
He said: "This is a truly sickening attack on a defenceless, frail lady as she slept in her own home.
"Mrs Winnall had nothing of note to steal; it was a senseless assault."
One neighbour told Sky News: "It's disgusting. Only the lowest of the low would do that.
"It's just scary that it can happen on your doorstep and that someone could do that to an old woman."
