A former recruitment boss has been convicted of harassing RBS chief executive Stephen Hester days after she was arrested for sending him poison.

Ruby Cooper, 52, sent two emails in breach of a restraining order which threatened to "flush out" Mr Hester and release the address of his children.

She had accused him of framing her after he had received a letter containing a vial of liquid, purporting to be poison days before. The email read: "I intend to flush you out Mr Hester, as I believe it is you behind this.

"You tried repeatedly to have me framed and fitted up over the past few years."

Cooper was not prosecuted for sending the vial but she was found guilty at Snaresbrook Crown Court of three breaches of a restraining order. Cooper, of Barnet, north London, had denied the charges.

Jurors heard she has spent nearly 20 years campaigning against the bank after being 'freaked out' by a member of their staff in the early 1990s.
