UK mass screening of police employees has led to nine criminal inquiries, chiefs say

Records of 307,000 officers, staff and volunteers checked against national intelligence database after recent scandals

Police chiefs have said a mass screening of more than 300,000 UK police officers, staff and volunteers has led to nine criminal investigations.

The records of 307,000 police employees were checked against a national intelligence database in an exercise after the cases of Wayne Couzens, the officer who kidnapped, raped and murdered Sarah Everard, and David Carrick, who became one of Britain's worst convicted serial rapists, despite repeated concerns being raised about him.
