"Apang was arrested based on material evidence and statement given by the other accused," said special investigation cell officer.
Apang, who was summoned to the cell on Aug 24, was arrested under non-bailable sections.
He was held under section 120b (criminal conspiracy), 420 (cheating), 468 (forgery), 409 (criminal breach of trust) of IPC read with B-2 Prevention of Prevention of Corruption Act.
Cell's officials informed, "We provided Apang with a set of questionnaires and despite three earlier summons he appeared before the SIC only today. He denied knowledge of facts or persons involved in the scam."
The scam relates to loss suffered by the public exchequer because of false and fraudulent hill transport subsidy bills, which were cleared without financial concurrence. Apang had been at the helm of affairs at the time.
