On April 1, a grenade attack occurred outside the Bharatiya Janata Party (BJP) office in Sector 37, Chandigarh, Punjab, India. The Punjab Police have arrested five individuals linked to the attack, which was reportedly orchestrated with support from Pakistan's Inter-Services Intelligence (ISI). The suspects include Balvinder Lal, Jasveer Singh, Charanjit Singh, Rubal Chauhan, and Mandeep Sharma. Authorities have identified two assailants who remain at large. The investigation revealed connections to international handlers in Portugal and Germany. During the operation, police recovered one grenade and ammunition, indicating a broader terror module. The attack, executed by two men on a motorcycle, resulted in damage to vehicles but no injuries. Forensic evidence and CCTV footage were instrumental in tracing the suspects. Khalistani extremist Sukhjinder Singh Babbar claimed responsibility for the attack, which police described as an attempt to disrupt peace in Punjab. The investigation continues to target the entire network behind the conspiracy.
