Three people including editor of an online news portal were sent to jail in a case filed under Digital Security Act on Sunday in Barishal.

Mamunur Rashid Nomani, editor of online news portal Barishal Khobor, and his two associates -- Kamrul Mridha and Labu Gazi -- were arrested from 30 Godown area in Barishal, police said.

Barishal City Mayor Serniabat Sadiq Abdullah along with his family members went for a walk in the area near Kirtankhola river around 1am on Sunday, said Md Nurul Islam, officer-in-charge of Kotwali Police Station. At that time, Nomani, Mridha and Gazi recorded a video of them without permission, the police official said.

When the mayor and his family sensed their presence, policemen who were present there chased the three and caught them.

According to locals, the three were allegedly beaten when they were caught. This correspondent, however, could not verify the claim.

Barishal City Corporation's ward 21 Councillor Sheikh Syed Ahmed, who was present at the scene, filed a case under the Digital Security Act against the three with Kotwali Police Station.

Police later showed the three arrested in the case and produced them before a Barishal court in the afternoon. The court then sent them to jail.

The mayor and councillor could not be contacted for comments, despite repeated attempts.
