A STALKER used Alexa to listen in on his ex before threatening to stab her new boyfriend and throw acid in her face, a court heard.
Hassan Mehmet, 35, harassed Shelby Laidlaw and warned he would pull her teeth out after he deliberately crashed her Jaguar in a motorway suicide attempt.
The couple had been in a relationship for 13 years before it ended in April.
That month, Mehmet was arrested for coercive and controlling behaviour and domestic common assault after it was alleged that he bit Ms Laidlaw on her head.
He was released on police bail but then embarked on his campaign of harassment.
