Jakarta. Sallywaty Rahardja, a manager at media group Mugi Rekso Abadi, or MRA, and an employee of graft suspect Soetikno Soerdarjo, was summoned by national anti-graft agency KPK for a questioning on Tuesday (31/01) as part of its investigation into a bribery scandal involving the purchase of a number of Garuda Indonesia aircraft.

Febri Diansyah from the Corruption Eradication Commission (KPK) said Sallywaty – a senior manager at MRA, a holding company for a number of media, lifestyle and entertainment firms – was summoned as a witness to give information on former Garuda Indonesia chief executive Emirsyah Satar.

KPK claimed Soetikno, who is also the founder of MRA and beneficial owner of Connaught International, an India-based consultant company, allegedly bribed Emirsyah in a series of aircraft purchases between 2005 and 2014.

During that time, Soetikno reportedly gave Ermirsyah $3.4 million in cash and other benefits.

The KPK did not disclose the topics of Tuesday's interrogation with Sallywaty.

Sallywati and two former high-ranking officials of Garuda Indonesia have been banned from leaving the country in the next six months due to the ongoing investigation.

Soetikno and Emirsyah were named suspects in the case on Jan. 19. after British engineering company Rolls-Royce apologized in a hearing at a London court for having paid bribes to middlemen to secure contracts in China, India, Indonesia, Nigeria, Russia and Thailand.

Soetikno is the alleged middleman who connected the flag carrier's boss to Rolls-Royce.
