Met police officer under criminal investigation for knocking down moped teen

A Metropolitan Police officer who used his car to knock a teenager off his moped in a “tactical contact” has been put under criminal investigation.

The unnamed officer struck the scooter to deliberately stop the 17-year-old youth riding dangerously in Erith, southeast London, in November last year.

…Scotland Yard said the recently-introduced tactic has helped stop dangerous chases and reduced moped crime in London by more than a third.

Looks effective to me.
