Sikh separatist Amritpal Singh arrested in Punjab after manhunt

Indian authorities have arrested a self-described Sikh separatist, Amritpal Singh, in the border state of Punjab after a month-long chase that prompted fears of a revival of a Sikh insurgency there. The issue has become a diplomatic flashpoint, with protests in support of Amritpal taking place in the United States, Britain, and Canada. Punjab is one of the wealthiest Indian states but has been saddled with a menacing drug epidemic and crippling debt, leading to an exodus abroad. In a vacuum of leadership, Amritpal was able to rise, state residents and experts say.
