Two security sources said Abdullah Mursi was arrested for questioning on charges of “spreading false news” in connection with an interview he gave to the Associated Press news agency last week which focused on his father’s detention.

In the interview, 23-year-old Abdullah said his father’s health had deteriorated due to prison conditions and that the family was rarely allowed to visit.

Former president Mursi has been jailed since he was overthrown by the military in 2013 following mass protests against his rule.

An Interior Ministry spokesman could not be reached for comment and no statement was issued by the public prosecutor.

A judicial source said Abdullah was freed on a 5,000 Egyptian pound ($280) bail without being charged.

His brief detention came amid a crackdown on dissent that has swept up Islamists and liberal activists and which rights groups say is the worst in modern Egyptian history.

Abdullah’s brother Ahmed said police arrived at the Mursi home at 7 a.m. while the family were asleep. They broke into the villa, pointed guns at the driver and gardener while three officers in plainclothes woke Abdullah up, he said.

Last year, an appeals court ordered Mohamed Mursi jailed for 25 years in a final ruling on charges of spying for Qatar. He was already serving a 20-year sentence after being convicted over the killing of protesters during demonstrations in 2012.

Abdullah, the youngest of Mursi’s five children, served a one-year sentence after he was arrested in 2014 on charges of drug possession.

Another son, Osama, is in prison and was among hundreds sentenced last month to death or jail in connection with protests against his father’s overthrow. He received a 10-year sentence which he plans to appeal against.

After Mursi’s ouster, then-army chief and now President Abdel Fattah al-Sisi unleashed a crackdown on his Muslim Brotherhood.

Sisi’s supporters say the president, who was re-elected in March, has been trying to combat an Islamist insurgency and restore order following years of chaos after “Arab Spring” demonstrations forced former president Hosni Mubarak to step down in 2011.
