On Wednesday, February 23, the Tehran home of Ronaghi Maleki, a freelance blogger and freedom of expression activist who posts reports critical of the government on social media, was raided by unidentified security forces who took him to an unknown location, according to news reports.

The CPJ (Committee for the Protection of Journalists) condemned the detention.  “With the arrest of Seyed Hossein Ronaghi Maleki, the Iranian government is seemingly continuing its absurd practice of arbitrarily detaining journalists without charge,” said CPJ Program Director Carlos Martinez de la Serna, in New York. “Authorities must release Ronaghi Maleki immediately or at least reveal his location and any charges against him and allow all Iranians to freely access the internet.”

The actions follow a Twitter thread by Ronaghi Maleki, posted in both Farsi and  English, which condemned the passing of the “User Protection Bill,” a controversial piece of legislation that restricts Iranians’ access to the internet and was ratified by parliament last Tuesday.

Authorities have not officially accepted any responsibility for Ronaghi Maleki’s arrest, no charges have been formally announced, and CPJ was unable to confirm where the blogger is being held, the reasons for his arrest, or which branch of the security forces arrested him.

At 11 a.m. on February 23, Ronaghi Maleki called his parents to say he was going to work, according to Reza Ronaghi, the blogger’s father, who spoke to the US Congress-funded Radio Farda, adding that his son had received several threatening calls in recent weeks and told his family that he might be arrested again soon.

When Ronaghi Maleki’s family was unable to get in touch with him, they went to his apartment later that evening where they found the home ransacked and noted that his computer, laptop, hard drives, and several notebooks were missing, according to Hassan Ronaghi, the blogger’s brother, who spoke to CPJ by phone.

“Hossein’s life is at risk because he suffers from several health conditions including kidney, lungs, blood, and digestive issues and we don’t know if the kidnappers will give him his medicine,” Hassan Ronaghi said, adding that the blogger’s family asked the Iranian Ministry of Intelligence about Ronaghi Maleki’s arrest and status, but they have not received a response yet.
