Quote from BBC article:
A criminal inquiry into the Volkswagen emissions scandal is looking at "fewer than 10" possible culprits, according to a report.
A spokesman for the prosecutors' office in Germany said "more than two, but a lot fewer than 10" staff were being targeted, the AFP news agency said.
The comment followed reports this week that up to 30 people may be involved.
