Google executive Wael Ghonim may be held captive in Egypt, and despite his unknown whereabouts, he has been named a spokesperson of an Egyptian protest group.
Al-Jazeera reports that Ghonim's family has received "terrorizing" midnight phone calls from his captors that say Ghonim is being "taught a lesson".
Khalen Wassef of CBS news was told by a leader of the "6th of April" youth movement group that Ghonim has been named their spokesperson in order to pressure Egyptian authorities to release him.
A senior member of the group told Wassef Thursday morning that if government leaders "want to talk to us, talk to Ghonim."
The Egyptian government has not confirmed that Ghonim is being held.
Ghonim is Google's head of marketing for the Middle East and North Africa. He flew to Egypt to take part in the protests, where he regularly posted what was happening on his twitter account.
Ghonim's ominous last Twitter post before he went missing last Friday said "we are all ready to die."
Google has confirmed that Ghonim is missing and has set up an email address for information leading to Ghonim's whereabouts: firstname.lastname@example.org as well as a U.K. phone number: +44 20 7031 3008.
