SINEAD O’Connor told fans she was being tormented by a stalker days before her death.
Pals said the singer was scared of the woman who was pretending to be her online.
A source said: “Sinead felt very uncomfortable. She had started a new life in London but this person was making her feel on edge.
“Sinead confided in people and said she’d had gifts she believed to be from this person. It was upsetting.”
The Nothing Compares 2 U star tweeted on July 12: “There is one stalker. Female. Violent: again, NEVER engage with anyone claiming they know me without asking my management.”
