Scotland Yard has closed a case involving charges a 20-year old Metropolitan Police Service cadet used racial slurs in front of colleagues while at their training facility.

The cadet was confronted, and quit. Says Scotland Yard:

The Metropolitan Police Service will not tolerate discrimination or abuse in any form from its staff or officers. Whilst every case will be treated on its merits, anyone found guilty of such behaviour must expect to be required to resign or be sacked.

In other words: No slurs, Sherlock.
