The bank asked Ms. Lindsey about their ties in 2019 during an investigation into some of Mr. Singh’s personal financial transactions, including one involving her. Citi did not report any financial wrongdoing by either one to regulators. Ms. Lindsey said at the time that the two were just friends, according to Mr. Costiglio, the Citi spokesman.
In her lawsuit, Ms. Lindsey alleged that Mr. Singh had extended control over her life at work. Mr. Singh berated Ms. Lindsey for speaking to her mentor, who also happened to be his boss, according to the suit; when a Citi investigator looked into the sexual harassment concerns raised by Ms. Moran, the managing director, Mr. Singh instructed Ms. Lindsey not to cooperate, Ms. Lindsey told The Times.
On Nov. 6, 2022, after Ms. Lindsey told Mr. Singh that she was ending the relationship, he began threatening to tell their bosses at Citi about it, according to the lawsuit.
“It’s over for u,” Mr. Singh said in one text message viewed by The Times, declaring that he would share details about their relationship with other managers. “Damage done.”
It is not clear what Mr. Singh told superiors. But after receiving dozens of texts and calls from Mr. Singh over four days, on Nov. 10, Ms. Lindsey told senior managers about the relationship and filed a report to H.R., according to the suit.
On Nov. 22, Mr. Singh resigned from the bank. His boss, Tim Gately, Citi’s head of sales for the Americas for stocks, told employees that Mr. Singh had resigned for “personal and family reasons,” according to Ms. Lindsey’s suit. “We’re all very sorry to see him go,” he added, “but it was his decision, and we wish him well.”
