"Odisha Crime Branch arrests Madabi Bandi, a hard-core Maoist in connection with Sunki landmine blast of February 2017," Crime Branch DG BK Sharma tweeted.
Sharma said the blast was targeted at police vehicles but refused to divulge the place from where the rebel was arrested.
The Maoist was operating in Chhattisgarh's Dantewada region and a reward of Rs 4 lakh was announced for his arrest, he said.
The officer said the Maoist was produced in sub- divisional Judicial Magistrate (SDJM) Court in Korapur and sent to jail.
