At least 11 people including five security personnel were injured in a clash in Gaushala Municipality-4 of Mahottari district on Monday.

The clash occurred during a demonstration by locals and relatives of a woman, 25-year-old Aarati Devi, who died on Friday night.

They have demanded action against her in-laws, claiming the woman died due to torture by her husband, mother-in-law and sister-in-law, not by consuming poison.

Mahottari Police said the clash ensued after police stepped in to take the situation under control as protesters vandalised the house of murder-accused Umesh Sah.

Police Inspector Saroj Rai of Mahottari District Police Office said security personnel fired nine rounds of bullets into the air and lobbed 13 teargas shells in a bid to take the situation under control.

Security personnel from District Police Office have been deployed to maintain peace, said Rai.
