A lawyer representing Indonesian graft suspect Muhammad Nazaruddin says he has been denied access to his client.

Nazaruddin, the former treasurer of the governing Democratic Party, was brought back to Indonesia Saturday on a chartered plane from Bogota, Columbia where he was arrested last Sunday after months on the run.

His lawyer, O.C. Kaligis, told reporters Sunday that the authorities at a detention facility in Depok in West Java have denied him the right to speak to Nazaruddin.

Indonesia's anti-corruption agency said last week it wanted to be the first to question Nazaruddin.

The 32-year-old Nazaruddin fled to Singapore in May while being investigated on suspicion of soliciting almost $3 million in bribes in connection with the construction of an athletes' village for the 2011 Southeast Asian Games.

He disappeared soon after that. But while in hiding, he proclaimed his innocence and in turn made graft allegations against several high-ranking Democratic Party members.

Nazaruddin's case has been a major embarrassment to the government of President Susilo Bambang Yudhoyono, who was re-elected in 2009 on a promise to clean up corruption in the government.

The president has ordered full protection for Nazaruddin while authorities probe the games scandal.

No trial date has been set.
