According to the FBI, Singh was wanted in connection with multiple terror attacks in Punjab, India. He is suspected of collaborating with Pakistan’s Inter-Services Intelligence (ISI) and the Khalistani terrorist group Babbar Khalsa International (BKI).
He had been evading capture by using untraceable burner phones and encrypted applications. The agency also confirmed his involvement in a grenade attack that occurred in Chandigarh in September 2024, which was targeted at a retired Punjab Police officer, in collaboration with the Pakistan-based terrorist Rinda.
