An Egyptian journalist known for his critical views of the government said that police raided his parents' house and have arrested his brother.
Mohamed el-Garhy tweeted that the police came to the home of his parents, who live in a village northeast of Cairo, on Wednesday night and asked his father for his whereabouts.
When they were told that he was in the city, the police woke up his brother and took him instead.
"My brother Yasser has never been interested in politics and has not done anything wrong," el-Garhy wrote on Thursday, mockingly thanking Egyptian authorities for "maltreatment and humiliation".
The brother's whereabouts were not immediately known, el-Garhy said, and there was no statement from the police.
Despite the tightening of the grip on independent news media in Egypt, el-Garhy has often voiced criticism of President Abdel-Fattah el-Sisi's government and recently spoke up on his Facebook page in support of Shady el-Ghazaly Harb, a prominent political activist who has been detained for over a year.
In recent years, authorities have jailed dozens of Egyptian reporters and occasionally expelled some foreign journalists from the country.
Since coming into power following a military coup in 2013, el-Sisi, a general-turned-president, has overseen an unprecedented political crackdown, silencing critics and jailing thousands.
Rights groups and media watchdogs have repeatedly condemned the mass arrests and crackdown.
"The rate at which journalists are being arrested is unprecedented since Abdel Fattah el-Sisi became president," Sabrina Bennoui, the head of RSF's Middle East desk, said in a statement last month.
"The fact this crackdown on media personnel is continuing although the street protests have been suppressed is all the more worrying."
