The Metropolitan Police has apologized to Caroline Flack's family for failing to keep a record of the reasons for charging her with assault.
After receiving complaints from the late television presenter's mother, the Independent Office for Police Conduct (IOPC) conducted an investigation.
The review concluded that there was "no misconduct" in the Met's choice.
While under investigation for allegedly assaulting her boyfriend, Ms. Flack committed suicide in February 2020.
The 40-year-old was well-known for hosting Love Island, the Xtra Factor, and for taking first place in Strictly Come Dancing in 2014.
Prior to her passing in 2020, she was scheduled to appear in court regarding Lewis Burton, her then-boyfriend, and an alleged assault.
The Crown Prosecution Service (CPS) had suggested that she only get a warning.
She was instead charged with assault by beating after the Metropolitan Police in London appealed the CPS decision.
After hearing how Ms. Flack's mental health had declined as a result of her arrest, an inquest ultimately reached the conclusion that she had committed suicide.
A senior police officer testified at the inquest that there was no bias in the decision to charge her, despite Christine Flack's complaints that her daughter had been treated unfairly because of her notoriety.
The review found no evidence of misconduct, but an officer should engage in reflective practice, a Met Police spokesperson said in a statement to BBC News on Sunday. When appealing a CPS decision, it was necessary to review all case materials, record a fair rationale, and show that the decision was made objectively by looking into both aggravating and mitigating factors.
"The IOPC also requested that the Met apologize to Ms Flack's family for the lack of a record of the grounds for the appeal of the CPS decision.
"We have done so and we are aware of the effect this has had on them.
"We are waiting to find out if the IOPC will offer any suggestions for organizational learning.
"The family of Ms. Flack continues to be in our prayers and in our thoughts. ".
Ms. Flack's mother responded to the Met Police's apology by telling the Eastern Daily Press: "They have apologized for how they handled my complaint, but what they really should be apologizing for is the way Carrie was treated.". ".
The Chief Superintendent of the Met, Andy Carter, reportedly informed her that several changes have been made to the way officers appeal CPS decisions, according to The Eastern Daily Press.
