Jakarta – Following Tuesday's explosive testimony from rogue Indonesian tax official Gayus Tambunan that a company controlled by the family of controversial politician and businessman Aburizal Bakrie paid him $500,000 for favorable tax treatment, police say they will now investigate – later.

National Police Spokesman Sr. Comr. Marwoto Soeto told news portal Detik.com on Wednesday that coal miner Kaltim Prima Coal "must be summoned" in relation to the allegations aired during Gayus's corruption trial in which he is accused of illegally accumulating Rp 28 billion ($3.14 million).

"There will be developments in the Gayus' case based on what happened at the court hearing. We will summon KPC as part of the investigation," Marwoto said. The summons, however, would have to wait until the "trial is over," he said.

Police have previously stated that they did not intend to investigate Gayus's links to 40 companies, including three controlled by Bakrie.

Bakrie, a former cabinet minister and current chairman of the Golkar Party, has been plagued by persisting allegations of dodgy tax dealings and wielding his powerful political influence on behalf of his businesses.

KPC lawyer Aji Wijaya on Monday flatly denied Gayus's allegations, saying KPC never met or communicated with Gayus and certainly did not give him money.
