Detectives suspect the deceased were militants as they recovered weapons and a number of jihadi books from their possession.
Speaking to the Dhaka Tribune, Tangail district Detective Branch OC Ashok Kumar Singh said detectives set up checkpoints at several places in Madhupur as a security measure after receiving a tip-off that militants might attack a local church.
“The suspects were on a motorcycle and were crossing a checkpoint in Telki around 4:30am. As the DB members on duty at the checkpoint flagged them down, they took out machetes and attacked the detectives.
“When the detectives opened fire at the motorcycle riders in self-defence, they were severely wounded. Later they were taken to Madhupur Upazila Health Complex, where the on-duty doctors pronounced them dead.”
Detectives also found three rounds of bullets, two machetes and a number of jihadi propaganda books on the spot.
The DB official said their identities could not be ascertained immediately.
“We suspect they were members of some militant group. We are investigating the matter to find out more information.”
