Rapid Action Battalion (Rab) on Wednesday detained a teacher of Begum Badrunnessa Government Girls College for questioning on alleged spreading of disinformation on social media.
The detainee was identified as Ruma Sarker, an assistant professor of the college.
ASP (Media) Imran Khan of Rab headquarters confirmed the detention and said they took the teacher to Rab Headquarters for questioning.
He said Ruma Sarker allegedly spread an old video footage of Sahinuddin murder in Dhaka's Pallabi as the killing of 'Jatan Saha' during recent communal violence in Noakhali on social media.
Sahinuddin was hacked to death with sharp weapons by some miscreants after being called out to a garage at D-block in Mirpur-12 for resolving a land dispute on May 16.
