Pakistani journalist Sami Abrahim, who was known for his public support for former prime minister Imran Khan, was reported missing, according to his family and his employer.
The journalist's disappearance was first announced in a police tweet late Wednesday.
Karachi-based independent media firm BOL also claimed on Thursday that he was abducted. In a news announcement, BOL TV said unidentified men abducted Abrahim on Wednesday.
Abrahim's brother Ali Raza testified to police that eight people in four vehicles intercepted his brother's car on his way back home from work in Islamabad. Abrahim's driver was left unharmed.
The journalist also publicly criticized incumbent prime minister Shahbaz Sharif, who replaced Khan after a no-confidence vote in 2022.
RSF concerned over Imran Riaz's welfare
Abrahim's disappearance was the second since another pro-Khan journalist, Imran Riaz, went missing two weeks ago.
The international media watchdog Reporters Without Borders (RSF) expressed concern over the wellbeing of Riaz. It called on the Pakistani government to "ensure respect for the rule of law" by revealing where and how he was detained.
The Pakistani media community also demanded accountability for the murder of 50-year-old TV anchor Arshad Sharif in Kenya in October last year. The journalist was living in exile in the African nation to avoid arrest at home on charges of maligning the Pakistani military.
According to Kenyan police, its officers opened fire on Sharif's car after it failed to stop at a checkpoint, killing him in a case of "mistaken identity" during a search for a similar car involved in a child abduction case.
Pro-Khan protests
Back home, Khan's supporters clashed with police across the country earlier this month in protest against his arrest from an Islamabad courtroom. The protesters attacked public property, including a radio station in the city of Peshawar.
The protests only died down when the country's supreme court ordered Khan's release. A crackdown of Khan supporters followed soon after, arresting more than 5,000 individuals after the fact.
