The former husband of a British woman detained in Dubai for calling his new wife a "horse" had reported her to British police for alleged harassment nearly four years ago, it has emerged.
Laleh Shahravesh, from Richmond, south-west London, potentially faces jail after she appears in court in the United Arab Emirates on Thursday over allegations she insulted Samah Al Hammadi on Facebook.
Ms Shahravesh, 55, was arrested after touching down in a Dubai airport with her 14-year-old daughter on March 10 and was reportedly held under the nation's controversial cybercrime laws.
Officers confirmed that Ms Shahravesh's ex-husband, Pedro Correia Dos Santos, previously made an allegation about her to Scotland Yard.
"In October 2015, police were contacted by a 48-year-old man living in Dubai concerning claims of harassment against a 52-year-old woman living in London, who was known to him," a statement from the force said.
Police spoke to both parties and the case was closed without any arrests.
Ms Hammadi told the Daily Mail that they made a complaint to Dubai police after Ms Shahravesh refused to relent in her behaviour.
"She has been abusing him, sending him emails, even to his boss in the bank, saying I am a bitch, that I took him from her, that she doesn't have money. He sent emails asking her to stop. It did not stop," Ms Hammadi said.
Campaign group Detained in Dubai has taken up Ms Shahravesh's case, with chief executive Radha Stirling saying Ms Hammadi had "stubbornly refused" to drop the complaint.
Ms Shahravesh was married to Mr Correia Dos Santos for 18 years and they lived together in Dubai for eight months before she returned to the UK with their daughter.
A few months later, in 2016, she received divorce papers and saw from photos on Facebook that Mr Correia Dos Santos had remarried.
In one later post, written in Farsi, she said: "I hope you go under the ground you idiot. Damn you. You left me for this horse."
In March, Ms Shahravesh and daughter Paris travelled to Dubai for Mr Correia Dos Santos's funeral a week after his death from a heart attack. The mother was arrested and her passport was seized.
Paris wrote to Dubai ruler Sheikh Mohammed bin Rashid Al Maktoum pleading for her mother's release.
Speaking to the Mail Online this week, Ms Shahravesh said: "Never in a million years did I think I would find myself in this situation over something that was written three years ago."
