Egypt's authorities said on Saturday they were investigating accusations against the former prime minister, interior minister and information minister, state television reported.
It said travel bans were imposed on ex-premier Ahmed Nazif and former Interior Minister Habib al-Adli, who were both sacked by Hosni Mubarak before he stepped down from the presidency on Friday.
A travel ban was also imposed on Information Minister Anas el-Fekky, who had been re-appointed in a cabinet that was hastily sworn in as a sop to protesters.
