A chilling terror plot with possible international links has been uncovered after a grenade attack rocked the BJP’s Punjab headquarters in Chandigarh on April 1, with investigators pointing to a shadowy network spanning Pakistan, Germany, and Portugal.

The blast, which took place on Wednesday evening outside the party office in Sector 37, has now taken a far more sinister turn.

Punjab Police suspect the involvement of Pakistan’s intelligence agency ISI, while also confirming that foreign-based handlers operating from Germany and Portugal were orchestrating the attack.

According to officials, the attackers arrived on a motorcycle and hurled a hand grenade or an improvised explosive device (IED) before fleeing.

The explosion damaged multiple vehicles parked outside the premises, and shrapnel marks scarred the building’s walls. In a narrow escape, no casualties were reported.

Within hours, a high-intensity probe was launched. CCTV footage became the first breakthrough, helping investigators trace the attackers’ movements.

Meanwhile, a video allegedly recorded by the attackers has surfaced as Punjab Police term the Chandigarh BJP office blast a low-grade explosion.

In a coordinated crackdown, Punjab Police’s Counter-Intelligence Wing and Chandigarh Police arrested five suspects.

Director General of Police Gaurav Yadav confirmed that two of those arrested were directly involved in executing the attack.

Security forces also recovered a .30 bore pistol, live cartridges, a grenade, and explosive materials, indicating that the group was armed and operationally prepared for further strikes.

Sources reveal that the operation was not an isolated act but part of a wider, well-structured terror ecosystem.

Multiple “sub-modules” were active, each handling specific roles, from weapons procurement to logistics like arranging vehicles.

At the top of this chain were foreign handlers based in Europe, allegedly issuing instructions and coordinating the strike remotely.

Adding another explosive layer to the case, the banned Khalistani outfit Babbar Khalsa International has claimed responsibility.

In a purported social media video, member Sukhjinder Singh Babbar declared, “Punjab is the land of the Khalsa. Khalistan will become a reality one day.”

Authorities, however, have not yet verified the authenticity of the video and are examining it closely.

Police teams are continuing raids to track down absconding suspects, even as central agencies are expected to join the probe to unravel the full extent of the cross-border conspiracy.

The Chandigarh attack now raises serious concerns about the revival of coordinated terror modules with global linkages, putting security agencies on high alert.
