The Punjab Police, on May 10, have so far detained at least 18-20 suspects in connection with the Rocket Propelled Grenade (RPG) attack at Punjab Intelligence HQs in Mohali in Sahibzada Ajit Singh Nagar District of Punjab on May 9 night, reports The Times of India. A high alert has been sounded in Mohali as the Police did not rule out it as a terror attack. The Police have picked up 6,000 to 7,000 mobile dumps of three mobile towers in the vicinity of intelligence headquarters building between 7pm [IST] and 8pm [IST].
