A woman has died after she was allegedly almost beheaded in a grisly murder in Woking.
Neighbours said the victim was found with her "head almost severed" at the large home in Surrey, and it is understood they were given this information by medics.
Surrey Police said two have been arrested who were "known to the victim".
A knife was also recovered from the scene in Julian close, Woking.
The woman is thought to have been in her 70s and lived in the suburban street with her husband.
A statement read: "Officers were called to an address in Julian Close, Woking at 12.21pm following a concern for safety of a woman.
"On arrival a woman was found dead inside the property.
"Two men, known to the deceased, have been arrested on suspicion of murder and are currently in custody.
"A knife was recovered from the scene."
Inspector Andy Greaves, from Woking Police, said: "This afternoon a number of resources attended a quiet area of Woking following a serious incident within a home address.
"This investigation is in its early stages and it would be wrong to speculate on exactly what's happened, however what I am able to share is that this is an isolated incident which poses no risk to the wider public following the arrests made at the scene."
A devastated neighbour described the victim as a "sweet" woman.
Salvina Giordano used to work with the woman's daughter and said: "They [the woman and her husband] have been living here for years and have been a quiet family.
"I know the lady wasn't 100%. They were people that kept to themselves. I haven't seen her for years, but I think that's because she was frail.
"It is devastating because she was such a sweet lady, she was lovely. I am so devastated it was her."
The large home, with solar panels on the roof and a double garage, was sealed off by police as forensics combed the scene.
The victim's body was left at the scene to examination and was due to be taken to a mortuary later in the day.
Local Tory MP Jonathan Lord said: "I am very sorry indeed to hear about this suspected murder and I wish the police and the prosecuting authorities every success in making sure that any guilty parties are brought to justice and feel the full force of the law.
"It is obviously a horrendous case and the fact that it is so close to Christmas only increases that sense of shock.
"I am sure that I am joined by all Woking residents in offering my sincerest condolences to the family and friends of the lady who has died."
