The temples – Loknath Mandir, Kali Mandir, Ramthakurer Mandir, Doyamoy Mandir, and Anukul Thakurer Mandir – are located at Lalpur village in Ashuganj Upazila.
Police have detained three Lalpur residents – Muhammad Babul Mia, 21, Muhammad Rasel Mia, 20, and Muhammad Jewel Mia, 18 – for the attacks.
A case is being filed over the incident.
Ashuganj police OC Abu Zafar said a band of men vandalised one Debashish Das Sohel’s house in Lalpur on Wednesday claiming he had made derogatory comments on Prophet Muhammad on Facebook.
Sohel was accused in a case under the ICT [Information and Communication Technology] Act and was detained the same night.
Zafar added a group of stick-wielding men vandalised five temples in Lalpur on Friday night over the alleged defamation.
Dilip Dasgupta, a local, said some people brandishing sticks took out a procession in the village on Friday evening.
