Israeli media reported earlier this week that part of the disagreement between now-former Teva Pharmaceuticals CEO Jeremy Levin and the company's board of directors is that Levin ordered an investigation that involved lie detectors tests for some key employees and board members.

Israel's Channel 2 reported, according to the Globes, a business publication, that Levin was frustrated with the board's day-to-day involvement and its tendency to chat with reporters. A link to the Globes story is here.

Here is the key passage:

Six months ago, Levin demanded an investigation, which was carried out by Wizman Yaar Investigations. As part of the investigation, Israeli directors at Teva underwent polygraph tests and were questioned about telephone conversations, which were shown to them.

Every candidate to succeed Teva chairman Phillip Frost, and every person who considered himself to be a candidate, was required to participate in the investigation. Although the wide-ranging investigation of Teva staff was carried out with the board's consent, senior directors told "Channel 2" that they had no choice in the matter in order not to be considered as suspects. When the investigation was completed, the leaker was discovered and exposed.

Teva is based near Tel Aviv. The company has several facilities in suburban Philadelphia, including its Americas headquarters in North Wales.
