Naga Munchetty shared a warning with BBC Breakfast viewers about a distressing segment during Friday’s episode.
The presenter, 50, was placed under review in August following complaints of bullying over a three-year period.
She was accused of bullying a female colleague last year and making a “wildly unprofessional” off-air sex joke that left a co-worker “humiliated” in 2022.
Last month, it was claimed Munchetty will be allowed to remain at the BBC’s flagship morning show under strict conditions while an official investigation takes place.
The broadcaster has been continuing to front BBC Breakfast with her co-host Charlie Stayt and, on Friday, she introduced a heartbreaking segment.
The duo shared the story of former sub postmaster Jonathan Armstrong, whose life was “destroyed” by the Post Office scandal.
“The lives of thousands of sub postmasters were destroyed by the Post Office Horizon IT scandal,” Stayt said.
“Among them was Jonathan Armstrong. Despite being innocent, he never spoke publicly about his ordeal, which culminated in him trying to take his own life.”
Munchetty went on: “Jonathan died in October of a heart attack, without receiving his full and final compensation.
“Now, his wife and daughter have shared his story for the first time.”
She added: “A warning - understandably, this report does include references to suicide.”
The program then aired a pre-filmed interview with Sarah and Beck Armstrong, who are Jonathan’s wife and daughter respectively.
They described how Jonathan’s life was ruined by the scandal, which involved shortfalls in Post Office tills caused by the faulty Horizon accounting system.
Around 1,000 branch managers were prosecuted, 236 went to jail, and thousands more were wrongly accused of stealing from their branches.
Recalling the accusations against Jonathan, Sarah said: “We knew things were bad, we didn't know where we were going wrong.
“And we had spoken about us potentially [ending our lives] together, that we were quite desperate. We didn't know where else to go. We had maxed out, we had borrowed money.
“So, when I realised he hadn't come back, I thought that's what he'd done.”
Becky added: “Thank God he didn't jump. He was talked down.”
Munchetty presents BBC Breakfast alongside Stayt every Thursday to Saturday, having joined the show in 2014.
She has been accused of being “hard” and “bullying” her coworkers and came under fire for two alleged incidents over a three-year period, according to a number of sources.
In 2022, she is said to have used a crude word for a sex act and asked a colleague if they had done it.
Although the exact comment hasn’t been reported, one source told The Sun it was, “crass, inappropriate and wildly unprofessional. The person felt embarrassed”.
Munchetty was also accused of bullying a woman last year, with The Sun claiming she allegedly accused a younger staffer of stealing, without presenting evidence.
The source told The Sun: “It was humiliating. There was no evidence, no apology. The woman left not long after, completely demoralised”.
Last month, BBC bosses reportedly escalated their review into an official investigation into Munchetty’s alleged behaviour after more complaints were made.
It has now been claimed the broadcaster has assigned watchdogs to keep a close eye on Munchetty in the studios while the probe takes place.
She has been allowed to remain on-air but will have members of production monitoring her and is only allowed to speak to “specific people”, sources claimed.
The Standard contacted Munchetty’s representative for comment at the time of the report. A BBC spokesperson said: “We do not comment on individual HR matters.”
