On Wednesday evening, a Barclays spokesman, after being asked about Garrity's status at the bank, said, "Mr.Garrity is no longer with Barclays."
"I can't comment on the reason for his departure," said the spokesman, who also declined to say when Garrity left the bank's employ.
The father of Lucy's owner — who had been informed of Garrity's departure from Barclays — told CNBC that prosecutors told his family earlier this week that a grand jury had returned an indictment lodging eight felony charges against Garrity in conjunction with the cat case, as well as other charges related to his alleged violation of the protective order.
A spokeswoman for the Manhattan District Attorney's office declined to comment when asked whether new charges were being filed in the case, noting that "the case is open and pending." Garrity's lawyer did not immediately return requests seeking comment.
Garrity, who is in United States on a work visa, had worked at Barclays' offices in New York City since October 2014. According to his LinkedIn page, his responsibilities included "know-your-client screening," which includes verifying client identities at the bank.
