PICTURED: $20million CASH found stashed inside a bed in Massachusetts

About $20million in cash that was hidden inside a box spring in a Massachusetts apartment has been seized as part of a wide-ranging investigation into an internet telecom company that was actually a massive international pyramid scheme.

The cash was found Wednesday inside a Westborough apartment by investigators who had tailed a Brazilian man from New York. Cleber Rene Rizerio Rocha, 28, was charged with conspiring to commit money laundering. He could spend up to 20 years in prison and be fined twice the gross gain or loss.

He was held after an appearance in federal court Thursday pending a detention hearing scheduled for next week. His lawyer could not immediately be reached.

The cash seizure was made in connection with an investigation into TelexFree, a Marlborough, Massachusetts-based company that purportedly sold VOIP telephone service.

TelexFree had few customers and made most of its revenue from people buying into the company with a promise of payouts for posting online ads for it, prosecutors have said. They were paid with money from new recruits, often friends and family of earlier investors.

Although initially aimed at Brazilian immigrants to Massachusetts, authorities allege almost one million people worldwide were swindled out of nearly $1.8 billion.
