Rangamati: An angry mob torched over 100 houses in Langadu upazila on Friday over the killing of a Jubo League leader, leaving four people injured.

To avert further trouble, the local administration imposed section 144 in the upazila while the patrol of Army and Border Guard Bangladesh was beefed up.

Locals said Nurul Islam Nayan, organising secretary of upazila Jubo League who used to carry passengers on his motorcycle in exchange for money, was found dead by a road in Dighinala upazila on Thursday.

Mentioning that two Pahari young men hired Nayan's bike for going to Dighinala, they alleged that the duo killed him in a planned way.

The Bangalee settlers went on the rampage while heading towards the graveyard along with the body of Nayan for burial from the upazila headquarters around 9:30am today, said additional deputy commissioner Prakash Kanti Chowdhury.

They set fire to over 100 houses in the upazila headquarters and several villages, including Manikjorchhara and Tintila, he said, adding that four people were injured in the arson attack.

Meanwhile, police arrested three people over the attack.

A tense situation was prevailing in the area.
