Separatist Amritpal Singh remains missing but his close aide Joga Singh, who had escaped with him two weeks ago, was arrested today in Punjab. Joga Singh was caught in Sonewal near Ludhiana. When the police launched its crackdown on Amritpal Singh and his pro-Khalistan 'Waris Punjab De' outfit, the radical preacher had fled along with his driver Joga Singh and associate Pappalpreet.
