Qureshi, F. (2007). The impact of extended police stop and search powers under the UK Criminal Justice Act 2003. Policing, 30(3), 466-483.

The introduction of the UK’s Criminal Justice Act (CJA) 2003 extended police stop and search powers. It allowed officers to stop and search for articles concerning the commission of the offence of criminal damage. The purpose of this study is to examine whether the act produced a change in the extent and nature of stop/searches. The four key findings are that there was: a large increase in observed compared to expected stop/searches, an increase in the likelihood of individuals of an Asian or Asian British Pakistani origin and Black and Black British of African origin being stopped and searched relative to others. A decrease in the proportion of stop/searches resulting in arrest; and the distribution of arrests being patterned by the ethnicity of a suspect stopped and searched.
