Hungarian intelligence agency interviewed CEO linked to exploding Hezbollah pagers

She speaks seven languages, has a PhD in particle physics, an apartment in Budapest plastered with her own pastel drawings of nudes, and a career that took her around Africa and Europe doing humanitarian work.

Cristiana Barsony-Arcidiacono, 49, the Italian-Hungarian CEO and owner of BAC Consulting, told NBC News earlier this week that she did not make the pagers and said she was "just the intermediate."

After her company was revealed to have licensed the design for the pagers from their original Taiwanese manufacturer Gold Apollo, Barsony-Arcidiacono told NBC News that she didn't make them.

Hungarian intelligence services have conducted several interviews with the CEO of BAC Consulting, a Budapest-based company linked to deadly explosions of pagers used by Hezbollah members this week, the Hungarian government said on Saturday.

Taiwanese pager firm Gold Apollo said on Wednesday that the model of pagers used in detonations in Lebanon were made by BAC Consulting, adding it had only licensed out its brand to the company and was not involved in the production of the devices.

Since then, she has not appeared in public. Neighbors say they haven't seen her. Barsony-Arcidiacono has not responded to Reuters calls and emails and there was no answer when Reuters visited her private address in downtown Budapest. Her flat in a stately old Budapest building, where a door to a vestibule had been open earlier in the week, has been shuttered.

On Saturday the Hungarian government said that its intelligence services have conducted several interviews with Barsony-Arcidiacono since the explosions.

Hungarian government says that BAC Consulting was a 'trading-intermediary company'

Following publication of this story, Reuters again reached out to her but received no reply. The Hungarian government said on Wednesday that BAC Consulting was a “trading-intermediary company” that had no manufacturing site in the country and that the pagers had never been to Hungary.

Discussions with acquaintances and former work colleagues paint a picture of a woman with an impressive intellect and a peripatetic career in a string of short-term jobs in which she never quite settled down.

An acquaintance of hers, who like others who knew her socially in Budapest asked not to be identified, called her "Good-willed, not a business type." The person said she appeared to be someone who is always enthusiastic to try something new and readily believed things.

Kilian Kleinschmidt, a veteran ex-UN humanitarian administrator who hired Barsony-Arcidiacono in 2019 to run a six-month Dutch-funded program to train Libyans in Tunisia in subjects such as hydroponics, IT and business development, described hiring her as a big "mistake." After disagreements in how she managed staff, he said he let her go before her contract was over, which Reuters could not independently verify.

At her Budapest home, a steel outer gate encloses a small vestibule where life drawings of nudes sketched in red and orange pastels can be seen taped up on the wall. An inner door leading into her apartment was ajar when Reuters first visited the building on Wednesday, and closed when the reporter returned on Thursday. No one answered the bell.

A woman living in the building for the past two years said Barsony-Arcidiacono was already a resident when she moved in, and described her as kind, not loud, but communicative.

She practiced her drawing as part of a Budapest art club, though she hadn't attended for a couple of years, said the organizer of the group, who said she seemed like more of a businesswoman than an artist but was upbeat and outgoing.

A school mate of Barsony-Arcidiacono said she grew up in a family with a working father and housewife mother in Santa Venerina, near Catania in eastern Sicily, and attended high school nearby. He described her as a quite reserved youngster.

In the early 2000s she earned her PhD in physics at University College London, where her dissertation on positrons - a subatomic particle with the mass of an electron and a positive charge - remains available on the UCL website. But she appears to have left without pursuing a scientific career.

"As far as I know she has not done scientific work since then," Akos Torok, a retired physicist who was one of her professors at UCL and published papers with her at the time, told Reuters by email.

A resume she used to get the job working for Kleinschmidt included references to other post-graduate degrees, in politics and development, from the London School of Economics and the School of Oriental and African Studies, which Reuters was not able to verify.

She then went on to describe a string of jobs working on NGO projects in Europe, Africa and the Middle East.

In a separate CV on the BAC Consulting website, she described herself as a "Board Member at the Earth Child Institute," an educational and environmental charity in New York. The group's founder, Donna Goodman, told Reuters Barsony-Arcidiacono had never held any role there.

"She was a friend of a friend of a board member, and contacted us about a job opening" in 2018, Goodman said. "But she was never invited to apply."

That CV also described her as a former "Project Manager" at the International Atomic Energy Agency in 2008-2009, who organized a nuclear research conference. The IAEA said its records indicated she had been an intern there for eight months.

On BAC Consulting's website, which was taken down by the end of this week, the company gave little idea of its actual business in Hungary. Its registered address is a serviced office in a Budapest suburb.

"I am a scientist using my very diverse background to work on interdisciplinary projects for strategic decision-making(water & climate policy, investments)," Barsony-Arcidiacono wrote on her CV.

"With excellent analytical, language, and interpersonal skills, I enjoy working and leading in a multicultural environment where diversity, integrity, and humor are valued."
