Thanks to Josh for sending around 5:30pm:

“both cop and person pursued wreck badly, person chased runs off. Cop injured”

Update: Thanks to a reader for passing on the security footage:

Wow cannot believe what I witnessed earlier today at park and 11th. Thank god everyone was pretty much okay. Maybe that cop was going a bit fast… @redrocksdc #columbiaheights #caraccident
