BOGOTA, Colombia (CNN) -- "Easy money, fast and effective." 

Investors protest outside the headquarters of DMG, one of many companies accused of defrauding the public. 

That was the name of one of the businesses in which millions of Colombians deposited their life savings after being promised short-term returns of as much as 150 percent. 

But government officials say the businesses were pyramid schemes that raked in at least $200 million from 3 million people. 

The government has said it knows who most of those responsible are, but they have escaped. The government is tracking them down. 

Sergio Munoz is among those who lost their savings. 

"That was for my children," he said. "Now, it comes to light that they have robbed us. It was with complicity of the authorities who permit this -- knowing that it is illegal for it to be permitted." 

The government says the businesses defrauded the public by offering false promises of a sure investment. 

Wilson Rodriguez handed over the equivalent of $80,000 to a money man who offered him what he thought were assets in hotels and property in exchange. 

Now, he doesn't know whom to approach. 

"I don't even have enough to care for my family," he said. "I lent money and what I make from my salary goes to pay off debts. I have nothing. I lost everything." 

Infuriated investors have demonstrated outside the headquarters of several companies in question across the nation. 

Worried that the situation has already led to physical altercations and riots, President Alvaro Uribe asked that authorities act immediately to bring those responsible to justice.  QUESTIONS:
