Night started with a firearms job in Chesterfield following a stabbing - male detained but became violent on arrest. Assisted by @DerbysDogPolice PD Zane and his human. Spit hood required as subject was gobbing at out staff. Absolutely vile behaviour. Great kit to protect us. pic.twitter.com/pZPmgDl6rN— Derbyshire Armed Response Unit (@DerbyshireARU) March 12, 2019
