Medan – Around 100 people staged a rally Wednesday outside the North Sumatra legislative council in Medan in support of the Corruption Eradication Commission's (KPK) investigation of a Rp 102.7 billion graft case.

The case in Langkat regency allegedly implicates former Langkat regent Syamsul Arifin, now the North Sumatra governor.

The protesters from the Big Family of Indonesian Pancasila Society urged the council to set up a special committee to probe the graft case.

Demonstrator Misno, a resident from Langkat, questioned why the case remained resolved.
