The Metropolitan Police has been instructed by the Independent Office for Police Conduct (IOPC) to reinvestigate Caroline Flack's mother's complaint that her daughter was treated differently by police due to her fame.
The Love Island presenter was found dead in her north London flat aged 40 in February 2020.
A coroner ruled she took her own life after learning prosecutors were going to press ahead with an assault charge over an incident involving her boyfriend, Lewis Burton.
The day before her death Flack discovered she would be prosecuted over the charge that she hit Burton with her phone while he slept over concerns he had been cheating on her.
Friends of the star said she was expecting the case to be dropped after her lawyers applied for it to be thrown out.
Coroner Mary Hassell found that Flack killed herself because she knew she was being prosecuted and could not face the press coverage.
However, her mother claims she was treated differently owing to her celebrity status and effectively blames the police for her death.
Mrs. Christine Flack said she still wants to know why her daughter was charged with the assault – despite prosecutors initially saying she should be given a caution.
She said: "I just want those answers to make me feel better and to make me know that I've done the right thing by Caroline."
She added: "It leaves us really sad and really angry because we want to know why they charged her.
"I just want the truth out there. I know it won't bring her back but I've got to do it for her."
Asked if she feels the decision to charge her daughter contributed to her death, Mrs Flack said: "Oh, totally. Totally. She couldn't see a way out." adding that she had now lost trust in the force.
The Met has since announced that they will re-examine the element (being treated differently) of the investigative process.
