IC is police-speak for identifying the ethnicity of a person: identity codes include IC1 (White), IC3 (Black), IC4 (West Asian), IC5 (East Asian), but the term IC3 is used more specifically to refer to black males or an opp. BSide rapper '30' popularized the usage of this term in the song 'IC3'.
“We have one IC3 male, around 5ft 5in, wearing a black hoodie and a red baseball cap"
30: "On the lurk tryna fry me an IC3"
