A WOMAN began a ‘sinister’ stalking campaign against a colleague after an office romance ended, a trial heard.

Jessica Nordquist falsely told clients of Mark Weeks he was a rapist in social media posts sent under fake names, the jury was told yesterday.

And she was allegedly behind a series of anonymous warning emails, made to look as if they had been sent to both of them from a third party.

One told them to meet at a café, adding: ‘If neither of you show, we’re going to release your past secrets around the office. We will come for you.’ When Mr Weeks didn’t go, he got a message saying: ‘Tick tock, the rabbit’s got f***ed.’

Nordquist began dating Mr Weeks in August last year but they split in November, prosecutor Claire Robinson said. Soon after Nordquist revealed she was pregnant and he accompanied her to have an abortion, the jury heard.

Nordquist allegedly tried to resume the romance after Christmas but was rejected by Mr Weeks. She is said to have sent him a message saying: ‘I’m telling people at work I had an abortion and if they ask with who I’ll say you.’ The 25-year-old, who later bought a fake pregnancy belly online, did not name him in a post about the abortion.

But soon after, the emails and rape allegations began, said Ms Robinson, and became ‘more and more sinister’. Nordquist, who moved from the US to work at video advertising firm Unruly in east London, denies stalking, sending malicious communications and perverting the course of justice.

The trial continues at Snaresbrook crown court.
