Cairo: The detained ousted Egyptian president Hosni Mubarak was on Thursday asked to appear before a Cairo court along with his two sons on Tuesday. The military rulers were pushing ahead with investigations against the ex-president, in spite of his complaints of heart trouble.

The authorities, however, put off the shifting of the ailing ex-president, who is still reported to be in ICU in a hospital in Sharm al-Sheikh in view of his unstable condition.

Mubarak and his two sons were ordered to be detained for 15 days by the Prosecutor General pending investigations into accusation of corruption and abuse of authority.

Military sources said Mubarak was being shifted from Sharm al Sheikh to Cairo. It remains unclear whether the deposed president will be sent to a hospital or to prison.

A news agency said that army helicopters which had arrived in the Red Sea beach resort to shift him to Cairo left empty as Mubarak's health was reported to be unstable.

State television reported that Mubarak and his sons Alaa and Gamal would appear before a Cairo court on April 19 for questioning, with the Prosecutor General's office saying that ongoing investigations were into allegation of corruption, squandering of public money and abuse of authority for personal gain.

The state television did not divulge further details about Mubarak's health or about the investigations. It quoted the director of the Sharm al Sheikh hospital Mohmmad Fathallah as replying that the former president's health was "somewhat improving".
