The Illicit Gains Authority decided Thursday to impose a travel ban on ousted president Hosni Mubarak’s daughters-in-law, Heidy Rassekh and Khadiga El-Gammal.

Rassekh and El-Gammal, wives of Mubarak’s sons Alaa and Gamal respectively, have already been interrogated over charges of illegal profiteering.

Both women were prevented from leaving the country along with their children, Omar Alaa and Farida Gamal, pending further investigation.

Mubarak’s sons and a host of former government officials were incarcerated in Tora Prison weeks ago on multiple charges of corruption.

Mubarak, 83, who was toppled on 11 February after an 18-day popular uprising, is being held in Sharm El-Sheikh International Hospital in light of his deteriorating health.

His wife, Suzanne, was detained for a period in the same hospital, but was released after several days. She is banned from travelling abroad also.
