A British former executive who raised questions about Commerce Secretary Howard Lutnick’s ties to convicted sex offender Jeffrey Epstein has died by suicide, according to The Banker.

Simon Andriesz, 57, a former Wall Street managing director who previously worked for a company affiliated with Lutnick, died last week, the outlet reported.

Andy Agathangelou, founder of the Transparency Task Force, which hosted whistleblower events with Andriesz, confirmed his death to the publication.

“It is with great sadness that we share the news that Simon Andriesz, a valued member of our community, passed away last week,” Agathangelou said.

Andriesz raised questions about business communications involving Lutnick and Epstein that he said had not been disclosed, according to the BBC.

Andriesz, a former employee of BGC Partners, the brokerage firm spun off from Cantor Fitzgerald that Lutnick led, identified a 2018 email chain in which Lutnick and Epstein discussed plans involving a startup business, the BBC reported.

According to the outlet, Andriesz shared his findings with the House Oversight Committee ahead of Lutnick’s scheduled appearance before the panel in May.

“The personal consequences of whistleblowing, and the retaliation I say followed, have been devastating for my family and me,” Andriesz said Aug. 9 while summarizing his findings.

The BBC also reported that Andriesz found Lutnick’s companies considered doing business with then-Prince Andrew in 2013. Andrew’s relationship with Epstein has been the subject of years of scrutiny.

Andriesz later said he was “completely shocked” to discover his own name in files related to Epstein.

The documents containing Andriesz’s name reportedly concerned interviews he gave the FBI during a dispute with BGC Partners, his former employer, according to the BBC.

Lutnick has condemned Epstein’s conduct and expressed support for his victims.

“I unequivocally condemn the conduct attributed to Jeffrey Epstein and everyone who participated in his illegal activities,” Lutnick said, according to The Banker. “The survivors of his crimes deserve our respect and support.”

Lutnick has denied any wrongdoing related to Epstein, telling the House Oversight Committee that he had “done absolutely nothing wrong, [or] inappropriate.”

The Commerce Department also told the BBC there was no evidence of wrongdoing.

Epstein, a wealthy financier and convicted sex offender, died in a Manhattan federal jail in 2019 while awaiting trial on federal sex-trafficking charges. Authorities ruled his death a suicide.

His longtime associate Ghislaine Maxwell was later convicted on federal charges related to helping Epstein recruit and sexually abuse underage girls.

Epstein’s contacts with prominent figures in politics, business, and international circles have continued to receive scrutiny, including through congressional efforts to examine government records related to the disgraced financier and his associates.
