According to Krebs on Security, 5 more Digital Currency Changers were taken offline (apparently seized by court order) along with Liberty Reserve as reported yesterday.

It is not known if additional arrests have been made around the world, but this may be indication that a press conference or news release will be made on Tuesday (this is Memorial Day weekend in the US) that US have executed a large takedown operation on various unlicensed e-Currency exchanges as major enablers of crime and cybercrime.

Those denialists may want to watch this report from Puerto Rico's channel 7 news:
