CBI's Joint Director, Rishiraj Singh, told reporters that to secure extradition of Atala from Peru would not be difficult for the agency.
CBI is probing two cases of policemen-drug peddlers nexus here, following a High Court order. Local Crime branch which was earlier handling the probe was not able to make progress.
Singh said that although India did not have extradition treaty with Peru, the government of that country can be approached and requested to hand over the accused. Also, Interpol can be approached for this purpose, he said.
"Even if there is no treaty, there is a Memorandum of Understanding signed with certain countries, which is equivalent to a treaty," the joint director said.
Atala is suspected of selling drugs sourced from the Goa police storage. Seven policemen were arrested in this case.
CBI is also investigating another case of police-mafia nexus, involving drug dealer David Driham alias Dudu.
Singh said that the process of collecting documents pertaining to these two cases from Goa police was on.
"We will also move the court to have set aside the chargesheet filed in Dudu case by police," he said.
On Monday, CBI will take over the third case in the series, involving Police Sub Inspector Sunil Guddler, who was caught on camera hobnobbing with Dudu's sister and girlfriend. Guddler too was suspended.
Singh said fresh FIRs would be filed in all three cases. He assured that even politicians would not be spared, if they were found to be involved.
Lucky Farmhouse, Atala's former girlfriend, had alleged that state Home Minister Ravi Naik's son, Roy, was involved in the case in which Atala is an accused.
