The doctor who may face charges over Michael Jackson's death is under suicide watch at his luxury Las Vegas home.
Pals are keeping a constant watch on 55-year-old heart specialist Conrad Murray, 55.
They fear he may try to take his own life rather than face second-degree murder or manslaughter charges over Jackson's death.
A neighbour said he is believed to be on the edge of a breakdown.
"He won't come out because he can't come out," the Daily Star quoted the neighbour as saying.
"He's become the most hated man in the world," the neighbour added.
