The scandal comes at a time when President Juan Manuel Santos’ still-high popularity in opinion polls has taken a hit over perceptions of increased corruption and insecurity as well as his government’s response to heavy downpours that battered the Andean nation.
“This operation (the tax agency) will continue. It’s just one tiny arm of a large octopus,” Santos said.
The president, who took office last August, said 12 of the 17 suspects in the scandal had been captured after officials said former and current tax agents used fake firms to get tax refunds for falsified sales abroad.
Tax agency director Juan Ricardo Ortega said the graft scandal could have cost the country up to 1.5 trillion pesos ($850 million) between 2004 and 2010.
“It’s a fairly organized assembly of shell companies and identity theft,” Ortega said.
Santos came to power in 2010 vowing to combat corruption, and earlier this week he signed an anti-graft law, saying a large scandal was about to be unearthed.
In May, he said fraud estimated at $17 million was discovered in the public health system. On Thursday Santos said Colombia had stopped the “bleeding” of resources worth about $340 million a year.
Colombia ranked 78th out of 178 countries in a 2010 anti-corruption index from Transparency International, scoring 3.5 out of 10 — the same as China and Greece.
