Jacob “Kobi” Alexander, former CEO of Comverse Technology, is wanted in the U.S. on charges of bribery and criminal fraud. Alexander evaded arrest and fled to Namibia.

U.S. prosecutors have since added the new charges of bribery, obstruction of justice and witness tampering to Alexander’s roster of accused crimes. Alexander allegedly offered someone $5 million to take the fall for his fraud charges. His earlier fraud charges stem from the manipulation of stock options, and he also been charged with conspiracy and money laundering.

Alexander, an Israeli citizen and a permanent U.S. resident, was arrested in Namibia, but has been released on bail. U.S. prosecutors are seeking to have him extradited.
