Egyptian authorities Monday arrested the country’s agriculture minister over corruption allegations, security sources said, just after his resignation was announced.

The prime minister’s office released a statement earlier in the day saying Salah al-Din Mahmoud Helal’s resignation had been accepted on the instruction of President Abdel Fattah al-Sisi.

“He was arrested in connection with a corruption case involving illegal land licenses,” a security official said. “He is under investigation.”

Helal could not immediately be reached for comment.

Egypt, the world’s largest importer of wheat, has embarked on a series of reforms designed to strengthen an economy battered by political turmoil since an uprising toppled president Hosni Mubarak in 2011.
