Mike Nudelman/Business InsiderCharlie Shrem, the CEO of Bitcoin exchange site BitInstant, was arrested earlier today and charged with money laundering.
Among other things, Shrem serves as vice chairman for the Bitcoin Foundation, the unofficial custodian for the digital currency.
This afternoon the Foundation, which is based in California, released the following statement:
"We are surprised and shocked by the news today. As a foundation, we take these allegations seriously and do not condone illegal activity."
The Winklevoss twins also released a statement this afternoon - they'd led a major funding round for BitInstant. "We look forward to clearer regulation being implemented on the purchase and sale of bitcoins," they said.
