Two suspects have been identified in connection with the blast outside the Bharatiya Janata Party headquarters in Chandigarh, a senior police official said on Friday, adding that efforts are underway to apprehend them.

The explosion took place around 5 pm on Wednesday near the party office in Sector 37, when a suspected crude explosive device was hurled at the site. No casualties were reported.

An FIR has been registered under relevant provisions of the Explosives Act and the Unlawful Activities Prevention Act. Security was tightened in the area following the incident, with police cordoning off the site and deploying additional personnel. A team from the National Investigation Agency also inspected the location as part of the probe.

Investigators are examining an unverified video circulating on social media that appears to show one individual pulling the pin from a blue-coloured grenade and throwing it, while another records the act. The two are then seen fleeing moments before the explosion. However, the authenticity of the video is yet to be confirmed, and the suspects’ faces are not clearly visible.

CCTV footage has also captured individuals running across the road shortly after the blast, which may aid the investigation.

In a separate unverified social media post attributed to Babbar Khalsa International member Sukhjinder Singh Babbar, the outfit claimed responsibility for the attack. Authorities have not confirmed the claim.

Earlier, Senior Superintendent of Police Kanwardeep Kaur said preliminary findings suggest a small crude device was used. State BJP chief Sunil Jakhar described the incident as an “attack” on the party office, while Amrinder Singh Raja Warring condemned it as a matter of grave concern.

Police said further investigations are ongoing.

Raghav Chadha on Friday said he has been “silenced, not defeated,” a day after being removed as the deputy leader of the Aam Aadmi Party in the Rajya Sabha.

In a video message posted on X, Chadha alleged that his own party had sought to prevent him from speaking in Parliament. “Whenever I get a chance, I raise issues concerning the people in Parliament, including topics that are often overlooked. But is it an offence to talk about people’s problems? Did I commit any crime?” he said.

He further claimed that the party had formally communicated to Parliament that he should not be given an opportunity to speak. “The AAP has informed Parliament that I should not be given a chance to speak. I would like to tell them — do not take my silence for defeat,” Chadha asserted.

Questioning the move, he added, “I raised several issues that benefited the aam aadmi (common man). What harm did that cause the party? Why does anyone want to stop me from speaking?”

The development follows a letter sent by the AAP to the Rajya Sabha Secretariat on Thursday, seeking Chadha’s removal from the deputy leader’s post. The party has proposed Ashok Mittal, a Rajya Sabha MP from Punjab, as his replacement.

Sources indicated that the letter also recommended that Chadha should not be allotted speaking time in the House from the party’s quota.

Once regarded as a close confidant of Arvind Kejriwal and among the youngest Members of Parliament in the country, Chadha has played a significant role in party affairs, particularly in Punjab and during the party’s tenure in Delhi.
