Bandung, West Java – Deputy chairman of the Corruption Eradication Commission (KPK), Mochamad Jasin, said Tuesday that the body's strict grip on graft cases has forced corruptors to change their tactics.

Jasin said corruptors now evade KPK investigators by reducing electronic transactions as well as meeting in person instead of using mobile phones.

"There was a time when the (graft) money was usually transferred through banks, but now they go through money changers. They (corruptors and bribers) no longer use formal financial institution but meet in persons," he said.

Jasin admitted that the change in tactics required KPK investigators to work even harder, tailing targets wherever they go. "This new trend was seen with the case of lawmaker Bulyan Rohan who was arrested on June 30 at a money changer in Plaza Senayan," he said.

Bulyan was caught when he was collecting US$66,000 and 5,500 euros as a bribe for a procurement of 20 patrol boats for the Transportation Ministry.
