According to the sources, Rehman Bhola was taken into custody from North Nazimabad. CCTV footage circulating on social media shows police escorting him after the arrest.

Police sources said he was detained over allegations of involvement in the firing that erupted during Sunday’s confrontation between two groups of MQM-P workers at the party’s Bahadurabad headquarters.

Rehman Bhola was acquitted in the Baldia Town factory fire case only a few weeks ago.

The clash broke out after Anees Qaimkhani arrived at the party headquarters with his supporters while a meeting led by MQM-P Chairman Dr Khalid Maqbool Siddiqui was in progress.

According to reports, a heated exchange preceded a confrontation between supporters of the two groups after Siddiqui left the venue. The situation escalated into a physical altercation, and gunfire was also reported.

During the unrest, a cameraman from a private television channel was allegedly detained inside the party office, assaulted and stripped of his camera after recording footage of the firing. He was later released after allegedly being warned against making the video public.

Party sources also claimed that Sindh Assembly member Hafiz Ejazul Haq and National Assembly member Sabeen Ghori were subjected to abusive behaviour before the firing incident. The reported gunfire created panic in the area late into the night.

Following the incident, Siddiqui announced an emergency late-night press conference but cancelled it minutes later without addressing the media.

Police have yet to issue an official statement on the arrest or the charges against Rehman Bhola.
