The law(persons) were chasing a vehicle containing at least "3 black males who were heavily-armed and wearing body armor-" a source told CSW.
It happened in the areas of Armour and Paseo (where a police vehicle was damaged)- Virginia and Forest between 33rd and 45th Streets and speeds were reported at "60 m.p.h.."
Along the chase route- the suspects were reportedly throwing weapons and/or other unknown items from the vehicle
The chase ended around 45th Street and Virginia just after 5:15 a.m. when the suspects crashed their vehicle- bailed-out and ran.
All 3 were apprehended within a block or two of the Virginia crash-out location.
A KC-MO Fire department EMS crew was ordered about 10 minutes later for a "traumatic injury" suffered by one of the suspects.
That "traumatic injury" was to the "35-year-old male" suspect's "face-" and it involved "fractures" and "lacerations" and all my source can say is that "it wasn't caused by the crash" of the suspect's car- so I'll leave the speculation how the man's face got battered up to you.
We're awaiting a statement from a Federal official on what this chase and arrest of the suspects was all about.
