The London Police have arrested four persons, including a 40-year-old woman, in connection with the stabbing of retired Lt. Gen. KS Brar in London on the 30th of last month.

A Police spokesperson said, all four have been taken to a central London police station for interrogation.

Gen. Brar had led 'Operation Blue Star' 28 years ago to flush out pro-Khalistani militants from the Golden Temple.
