A Pakistani academic was arrested here on Saturday "for participating at a protest", he said in a social media post.
"There is an FIR against me for participating at the protest in Liberty against the killing of Professor Arman Loni," the post said, adding that he was taken into custody at 4 a.m. which is when he said "the police raided my house".
In the FIR, the complainant said that Jan was leading a group of 100-150 people that had blocked roads and chanted slogans against state institutions and intelligence agencies.
Ismail, who was in detention for nearly 30 hours, was released on Friday.
Jan, known for his political views and activism, was barred to speak at a cultural event last November.
