Egypt's prosecutor-general has released Abdullah Mohamed Morsi, the son of ousted president Mohamed Morsi, a day after he was arrested for alleged possession of hashish.
Morsi and his friend, Mohamed Emad El-Shamy, were arrested on Saturday afternoon at a security checkpoint in the Nile Delta's Obour City, Qalyubia governorate, where officials say they found two joints of hashish in their car.
Both men were released pending investigation after they agreed to give blood and urine samples for a drug test, a top prosecutor said. The results are due on Monday, state news agency MENA reported.
Prosecutors had earlier said the duo tested negative for cannabis consumption.
Abdullah's brother, Osama, condemned Saturday's arrest on his Facebook page, claiming the allegations of drug possession were being used to "taint the image of honest people."
According to police officials, El-Shamy is an employee at Raya Holding for Technology and Communications, a company owned by leading Muslim Brotherhood figure Hassan Malek.
Ousted president Mohamed Morsi is currently facing several trials for an array of charges, including espionage, incitement of murder and killing protesters.
