There are two known cases of HKPF using flashbang grenades. Once at PolyU on November 17th, and then 20 meters from the crush during the Yau Ma Tei Stampede on November 18th. The one used in Yau Ma Tei was a 9 Flash-Bang, whereas the one used at PolyU was a single flash.
Immediately after the previous clip ends, footage of the big crush in the YMT Exit A1 alley begins. It's absolute chaos. People are still trying to get into the alley from Nathan. That creates a separate pileup on Nathan Rd.— OSINT HK (@OSINTHK) December 8, 2019

"Cops threw something down towards the exit steps. there was a small flash and two very loud bangs – at least one landed on the steps maybe 2 metres away from me…. my eardrums were vibrating, the way they do when you’re too close to a large speaker." https://t.co/utco70I0Lw pic.twitter.com/wNCn8hDcOY— OSINT HK (@OSINTHK) November 24, 2019
