Attree, whose job was to offer support to victims of domestic violence, said Baird was “too scared” to report the alleged abuse and was “anxious” about police turning up at her house.
Attree told the court that Baird said she would go to a refuge but feared Trybus would find her, even if she was outside of Swindon.
On one occasion, Attree said Baird showed her a screenshot of a message which Trybus had sent her, which showed how long Baird took to get to her location, her location at the time and the length of her return journey.
Reading her notes from the time, Attree told Rebecca Fairbairn, prosecuting, that Baird described Trybus as “very intellectual”.
“Trybus has developed some kind of software which is what his line of work is,” she added.
Recalling a conversation when Baird had tried to leave Trybus, Attree said: “She told us she had gone to a hotel, she bought herself a new phone but he still showed up at that hotel.
“She’d not taken one of their vehicles and she had paid cash.
“[She had] no idea how he followed her despite turning off location and GPS tracker on her phone.”
Trybus denies any wrongdoing and the trial continues.
