Amy Winehouse's home has been robbed.

Following the "Rehab" hitmaker's death on July 23, copies of her unreleased tracks, lyric books and letters have gone missing from her property in Camden, north London -- which only 20 people, comprised of family, friends, security and police, have had access to -- and her management have also been unable to account for one of her favourite guitars.

The 27-year-old singer's father Mitch -- who is currently on a family holiday attempting to come to terms with his grief -- is said to be "livid" and has vowed to find the culprit.

An insider said: "This is such a sickening shock to the family. That someone would stoop so low. They can't get their heads around it.

"Mitch is livid. The family, record label and management are months away from deciding what to do with any unreleased music. For that to be taken out of their hands is horrible."

However, the 60-year-old former taxi driver is prepared to give the thief a chance to "do the right thing" and return the items before the police get involved in the matter.

The source added to The Sun newspaper: "Mitch is willing to give whoever has stolen the items a chance to do the right thing and put them back so it doesn't have to get messy."
