Indonesia's football association chief La Nyalla Mattalitti has been deported from Singapore, where he was said to have fled to after being named as a suspect in a graft probe in March.

Singapore's Ministry of Home Affairs (MHA) said on Tuesday (May 31) that Mr La Nyalla had overstayed his social visit pass and hence had committed an immigration offence in the Republic.

"He was deported from Singapore on Tuesday, May 31, after his immigration offence was dealt with in accordance with Singapore laws," said a ministry spokesman.

The Indonesian authorities confirmed that Mr La Nyalla was handed over to immigration officials at the Indonesian Embassy in Singapore and is en route to Jakarta, where he will be questioned by anti-graft officers and prosecutors.

The chairman of Indonesia's football association was named as a suspect in a graft investigation by the country's Corruption Eradication Commission (KPK) on March 16.

Mr La Nyalla surfaced in Malaysia a day later, and then in Singapore on March 29.

He is suspected of being involved in a grant worth 5.3 billion rupiah (S$535,300) from the East Java administration to the provincial branch of the Indonesian Chamber of Commerce and Industry (Kadin).

The grant was for the 2012 purchase of shares in Bank Jatim, which is owned by the province.

Mr La Nyalla, who is also the chairman of Kadin's East Java chapter, was placed on the commission's most wanted list after he ignored three KPK summonses to testify.

Indonesia and Singapore have signed an extradition treaty, but Indonesian lawmakers have yet to ratify it in Indonesia's Parliament.
