No criminal prosecutions for truck cartel (but that's not the end of the story)

Some months ago (in volume 12 number 5, to be precise) we reported that the OFT had launched an investigation into allegations of price-fixing in the truck market, and as part of that exercise an individual had  been arrested. In December the OFT announced that it was not going to charge him:

The OFT commenced a criminal cartel investigation under the Enterprise Act 2002 into suspected cartel activity in the UK involving commercial vehicle manufacturers in September 2010. Following a thorough investigation it has been determined that there is insufficient evidence for any individual to be charged with the cartel offence. Accordingly, that case has been closed. 

The OFT then - ominously? - adds:

The OFT's Competition Act investigation is continuing.
