Beijing "campaign" re license plates

[Lao Jia Hou]

was told the police confiscated some big bikes in Beijing during the last few days, another crackdown before the mid autumn festival / october national holidays?

Details are sketchy - rumor has it that a large police SWAT team moved in on an assembly of foreign biker-gang-types on Harleys, and confiscated several illegal bikes (I heard 10 motorcycles seized). Happened Saturday.

Doesn't sound like it was part of any normal campaign. Sounds very serious.

But I have only heard rumors, albeit from a reliable source.
