Susan Boyle was startled to find an intruder in her home yesterday (26.01.10).
The man was on the stairs as Susan returned to her modest house in West Lothian, Scotland, and upon being discovered turned and ran past the scared music star.
The 'I Dreamed A Dream' star had only just arrived back home after a day in the recording studio, laying down vocals for Simon Cowell's charity single to aid the victims of the recent earthquakes in Haiti.
A friend told The Sun newspaper: "Susan got home to find an intruder halfway up her stairs. She was with another female, who was dropping her off, and only expected to be with her for a couple of minutes - but it is just as well she was.
"Susan is unharmed but is obviously very, very shocked. The guy has seen her come in and bolted out straight past Susan."
Police were called and the Lothian and Borders force confirmed a man was being held last night.
The multi-million selling singer - who lives alone - is now worried she may have to quit her home over safety fears.
Local police previously fitted the property with a panic alarm after Susan spotted two strangers peering through a window last year.
Meanwhile, Susan has spoke of her "honour" at being able to contribute to Simon's charity single, a cover of REM's 'Everybody Hurts'.
The 48-year-old singer said: ""It is just awful what is happening in Haiti. I've seen some of it on the TV and it's so sad.
"To be asked to do this with all these talented singers is just great, it's such an honour. It would be lovely to meet Rod Stewart, being a fellow Scot."
Other stars appearing on the record include Robbie Williams, Mariah Carey, Leona Lewis and Kylie Minogue.
