Climate activist Sonam Wangchuk was arrested in Leh on Friday, two days after violent protests over the demand for statehood and inclusion of Ladakh under the Sixth Schedule of the Constitution left four people dead and 90 others injured, officials said.

Wangchuk was taken into custody by a police team led by Ladakh Deputy General of Police (DGP) SD Singh Jamwal around 2.30 pm, said officials. It was not immediately clear what charges were pressed against him.
