The report also finds that environmental issues cause 5.2 billion days of illness annually and cost the equivalent of 17.6 percent of the country's GDP in 2019
The incident was reported from Monohardi around 2am Thursday, said Sub-Inspector Jinnat Ali Jinnah.
The man was identified as 35-year-old Siddique Mia who was sentenced to 17 years in jail in a robbery case.
Locals say robberies are common in the area. They say they formed a mob after learning from a traveller that a robbery gang had taken up positions near the highway.
Locals chased the gang. They caught and beat Siddique while the others fled. The attack left him dead on the spot.
SI Jinnat said Siddique was sentenced to 17 years in jail over a robbery case in 2009.
Police have filed a murder case against unknown perpetrators over the incident.
