Demane Debih’s assistance helped lead to the prosecution of at least half a dozen others linked to the scheme.

Lavidas was accused of leaking company secrets to a friend who passed them on to Demane Debih. He was convicted and sentenced to a year and a day in prison in July 2020.

Tuesday’s SEC lawsuit was filed a little more than a week after an Israeli man linked to the scheme, Dov Malnik, was sentenced to 30 months in prison.

Taylor and Windsor, a couple who shared a London apartment, were charged by the U.S. in October 2019 and have yet to respond to the allegations.
