As we have all seen over the last few weeks, illegal fireworks are extremely dangerous. NYPD Intelligence investigators and our city partners are working to stop the flow into NYC. This recent seizure included two AR-15 rifles. Well done by all involved. pic.twitter.com/Upcwe1K8gT— Chief Terence Monahan (@NYPDChiefofDept) June 25, 2020
