"There's 20 of us and only one of you," Adrian Troy Kuru called out to the police officer responding to reports of gang members fighting in the street outside a Gonville address.
"F*** off or we'll f*** you over." Sergeant Damon Evans had arrived just as a group of 15 or so Black Power members spilled out on to the street. Other patrol cars had been past earlier and not seen much activity.
"These types of jobs do not occur regularly, but they do happen from time to time," Mr Evans told the Chronicle.
As he arrested 30-year-old Kuru following the disturbance in the early hours of November 16, Kuru struggled while being handcuffed and told him he knew where he lived and where his children were.
"I've been threatened a number of times," said Mr Evans, recalling some of the more risky aspects of his job.
