"He will be summoned as a witness in the near future," said the KPK spokesman in a written statement issued on Friday.
According to the KPK official, he will be questioned as a witness in a bribery case involving KPK investigator Steppanus Robin Pattuju.
Considered as a key witness, Azis was the one who introduced Robin to inactive Tanjungbalai Mayor M Syahrial.
According to reports, the Functional Groups (Golkar) Party lawmaker allegedly also gave Rp 3.15 billion to Robin.
"The exact date will be informed later," Ali said.
