CAIRO - Egyptian authorities on Thursday arrested the country's former information minister and the chairman of state TV and radio on corruption allegations, the latest moves by the country's ruling military against senior officials of Hosni Mubarak's ousted regime, security officials said.

Authorities also referred to trial two former cabinet ministers and a one-time top official of Mubarak's political party. They'll face corruption charges, the security officials said.

Thursday's arrests of Anas al-Fiqqi, the ex-information minister, and Osama el-Sheikh, the state TV boss, were widely expected. Al-Fiqqi was placed under house arrest earlier this month and el-Sheikh was banned from traveling abroad Wednesday, steps that often precede a criminal investigation or a trial.

Al-Fiqqi was a confidante of Mubarak and his powerful, one-time heir apparent son Gamal. Under his and el-Sheikh's stewardship, state TV persistently discredited the young organizers of the 18-day uprising that forced Mubarak to hand power to the military after nearly 30 years of authoritarian rule.

Egypt's media have been buzzing with reports of spectacular corruption by members of Mubarak's regime as well as businessmen linked to his government. Authorities are inviting Egyptians to come forward with evidence of alleged corruption by the toppled regime, pledging not to reveal their identities.

Mubarak himself has been swept up by the anti-graft campaign that has followed his stunning ouster. Earlier this week, authorities froze his assets abroad, as well as those of his wife, two sons and their wives.

The security officials said the al-Fiqqi investigation looked into the fate of 2 million pounds (about US$340,000) he collected in donations to support a film festival in Cairo. Al-Fiqqi never presented documents explaining how he spent the money, said the officials, who spoke on condition of anonymity because they were not authorized to speak to the media.

El-Sheikh, said the officials, allegedly used state money to privately produce TV programs.

The arrest of the two followed Wednesday's imposition of a travel ban on a former prime minister -- Atef Obeid, who served as premier from 1999 to 2004 -- and long-serving ex-culture minister Farouq Hosni. The ban on leaving the country was also slapped on nine businessmen and el-Sheikh.

Also Wednesday, an angry crowd of hundreds taunted three former high-ranking members of Mubarak's regime when they arrived in court for a corruption hearing, screaming "thieves" and "you robbed our money."

The three former officials who appeared in a Cairo Criminal Court -- ex-Housing Minister Ahmed Maghrabi, former Tourism Minister Zuheir Garana and steel tycoon and prominent ruling party leader Ahmed Ezz -- wore white prison uniforms and sat in a metal cage as a judge issued a ruling blocking any commercial dealings in their properties.

On Thursday, authorities referred Maghrabi and Ezz to trial along with Rashid Mohammed Rashid, a former trade and commerce minister. Also going to trial are the ex-chairman of a media group that publishes a state newspaper and three businessmen.

The officials said the six are facing charges of illegally amassing wealth and squandering state funds. No trial date has been set.

The six are among some two dozen ex-ministers and business leaders who are under investigation. The protesters who ousted Mubarak often mentioned corruption as a key motive behind their movement.

The popular anger felt against such former power brokers was evident Wednesday.

As the vehicles carrying Maghrabi, Garana and Ezz drove through the streets of Cairo to the courthouse, dozens of cars followed them honking and people chanted "there are the thieves."
