Explosive devices

The criminal complaint includes images of the two suspects and references video that allegedly shows them throwing two devices toward the protest area. 

Federal prosecutors allege the pair attempted to detonate two improvised explosive devices Saturday near the mayor’s Upper East Side residence during dueling protests outside Gracie Mansion.

Authorities have said the case is being investigated as an act of ISIS-inspired terrorism. 

The criminal complaint includes images of the two suspects and references video that allegedly shows them throwing two devices toward the protest area. 

What they’re saying:

According to investigators, one device was ignited in a crosswalk at East End Avenue and East 87th Street and another was deployed on the west side of East End Avenue between East 86th and East 87th streets. No injuries were reported.

The backstory:

Preliminary testing by the NYPD bomb squad and FBI special agent bomb technicians determined the devices were improvised explosive devices, not smoke bombs or hoaxes. Officials said at least one device contained triacetone triperoxide, or TATP, a highly volatile homemade explosive that has been used in attacks worldwide.
