The fugitive former chief executive of Comverse Technology Inc. has been captured in Africa, U.S. officials announced Wednesday.

The arrest of Jacob "Kobi" Alexander in the Republic of Namibiawas announced by the U.S. attorney's office in Brooklyn. Details were not immediately available.

Alexander, a dual citizen of Israel and the U.S., is a founder and former chief executive of Comverse, a leading maker of voicemail software based in the United States. He was wanted in the U.S. on charges of manipulating stock options for personal gain.

Two other Comverse executives have turned themselves in to U.S. authorities, but Alexander disappeared after reportedly having transferred $57 million to Israel.
