The Abingdon Roads Policing tackled the crime in Oxford today (October 19) and took to social media to share the outcome.
The team said one man was arrested on suspicion of immigration offences, but did not provide further details.
Elsewhere, multiple electric bikes, which were not pedal assisted, were seized as they were not insured.

Another moped failed to stop, the team added.
An electrically assisted pedal cycle or e-bike must have pedals that can be used to propel it, a maximum motor power of 250 watts, and stop providing electrical assistance once the bike reaches 15.5mph.
The consequences of riding an illegal e-bike include fines, penalty points or even prosecution.
