CAIRO — An Egyptian activist and blogger known for documenting police abuse was detained on Wednesday, security officials said, the latest in a new wave of arrests following elections earlier this year.

Wael Abbas was taken from his home in a Cairo suburb on accusations that include disseminating false news and joining an outlawed group, the officials said.

The Arabic Network for Human Rights said police raided Abbas’s home at dawn, seizing his computer and mobile phones. It said he was blindfolded before being taken to an unknown location.

Abbas has campaigned against torture in Egypt for well over a decade, before and after the 2011 uprising that toppled longtime dictator Hosni Mubarak. He has published graphic videos showing torture and police abuse on his blog, misrdigital.com, and has been detained on a number of occasions.

His YouTube account was shut down in 2007, resulting in the removal of hundreds of videos showing protests and abuses by security forces. In December, he wrote on Facebook that Twitter had suspended his account without providing an explanation.

Amnesty International on Wednesday condemned Abbas’s detention, saying his arrest is part of a crackdown by Egyptian authorities on freedom of expression.

Authorities have arrested a number of secular activists since President Abdel-Fattah el-Sissi was reelected to a second four-year term in March. He faced no serious challengers, after several potentially strong candidates were arrested or intimidated into withdrawing from the race.

Earlier this month, Egyptian police arrested two prominent activists, Shady el-Ghazaly Harb and Haytham Mohamedeen, on an array of charges including belonging to an outlawed group and insulting the president. Shady Abu Zaid, a young comedian, was arrested on accusations that include spreading false news.

The latest arrests come amid a wider crackdown on dissent since Sissi led the military overthrow of a freely elected but divisive Islamist president in 2013.
