Tarqeq Releases New Report

“The Black Friday Web” presents a comprehensive investigation of the 1993 Mumbai bombings, using a network-analytic approach

Tarqeq Research LLP released its first Quarterly Report, “The Black Friday Web: A Network Analysis of the 1993 Mumbai Bombings,” today. One of the first of its kind globally, the report looks at the worst terrorist attack on Indian soil till date—the 1993 Mumbai bombings that killed 257 people—using network-analytic methods. The report is based on an in-house database of 220 individuals who Indian law enforcement had–at various points–charged with involvement in the attacks. The in-house database also contains more than 1370 distinct links between these individuals, which were reduced to 605 key ones using a specific procedure.

Using an open-source software, the database was analysed to obtain centrality measures associated with all actors allegedly involved in the 1993 attacks. The report also makes some specific observations which could aid Indian law enforcement authorities and security services in uncovering the broader conspiracy behind the 1993 attacks.

Research and advisory firm Tarqeq Research LLP deploys innovative concepts, methods, and tools from emerging and established mathematical, computational, and natural sciences to offer clients bespoke reports, virtual and in-person briefings, regular monthly briefs and quarterly reports, and training services around a range of subnational, national, and transnational security issues.
