A man who has been obsessed with musician Vanessa Mae for 10 years broke a court order to stay away from her, West London Magistrates have heard.
Martin kept track of Ms Mae's movements in west London
David Martin sent her letters, followed her as she walked her dog and kept track of her movements in London.
A restraining order was imposed last year on Martin, 56, of Brighton, East Sussex, who admitted harassing her.
He was arrested when Ms Mae's boyfriend said he saw him near her Kensington home. Sentencing has been deferred.
Prosecutor Benedict Leonard told the court Martin's obsession with the 25-year-old classical violinist began more than 10 years ago.
Letters 'not threatening'
He had since sent her letters and CDs and followed her when she took her dog for a walk, the court heard.
Mr Leonard said: "He has badgered her, attended concerts, communicated with her management company claiming to be a member of the family, speaking to them on first name terms and claiming he wants to talk to the victim."
His trial heard there was no suggestion he was threatening, but Ms Mae had found his numerous letters "distressing".
Martin served five months on remand last year while waiting to be sentenced for harassment.
A rehabilitation order and a restraining order banning him from contacting Ms Mae, her fan club or going to her concerts or near her homes indefinitely were also made.
Martin was remanded in custody while psychiatric reports are drawn up. He will be sentenced on 24 August.
