Egyptian state television is reporting that the country's former prime minister - who served under the nation's toppled Islamist president - has been arrested to serve a one-year prison sentence.
The broadcaster reported Hesham Kandil's arrest on Tuesday.
The case goes back to 2011 when a court ruled in favour of reversing deals struck by ousted autocrat Hosni Mubarak when his government sold a textile company to a Saudi investor.
A court sentenced Kandil to one year in prison for failing to implement the court order. The sentence was issued before a popularly-backed military coup overthrew President Mohammed Morsi on July 3.
Morsi appointed Kandil, a US-educated engineer who was an unknown technocrat and former water minister, prime minister in July 2012.
