Harpreet Singh, also known as Happy Passia, a most-wanted terrorist involved in over 14 recent grenade attacks in Punjab, India, was arrested on Friday in Sacramento, California. According to an announcement by the FBI Sacramento on X (formerly Twitter), Singh is accused of participating in several terror attacks in Punjab and is allegedly linked to two international terrorist organizations.

The FBI confirmed that Singh entered the United States illegally and took measures to avoid detection, such as using burner phones. "Today, Harpreet Singh, an alleged terrorist responsible for terror attacks in Punjab, India, was arrested by the FBI and ERO in Sacramento,” the FBI stated. “Linked to two international terrorist groups, he entered the US illegally and used burner phones to evade capture."

Singh has also been named in a chargesheet by the National Investigation Agency (NIA) in connection with the grenade attack in Chandigarh in September 2024. The attack, which targeted the residence of a retired Punjab Police officer, was reportedly orchestrated by the terrorist group Babbar Khalsa International (BKI).

The NIA's investigation revealed that Passia, operating from the US, and Pakistan-based terrorist Harwinder Singh Sandhu, alias Rinda, were the masterminds behind the attack. The two are alleged to have provided logistical support, funds, and weapons to operatives in India. According to reports, they directed local recruits—Rohan Masih and Vishal Masih—to conduct reconnaissance and execute the attack.
