Patna, March 9 (IANS) A day after security forces killed four Maoists, police stations across Bihar have gone on high alert, police said on Thursday.
The police have also launched a combing operation against the Maoists, the police said.
The Central Reserve Police Force (CRPF) shot dead on Wednesday the four Maoist guerrillas in the Banskatwa forest area in Gaya, about 100 km from here.
"Police stations have been directed to be on alert in view of the killing of Maoists because they may target police stations to take revenge," a police official said.
It was the first major successful operation against Maoists in Bihar since last year.
Last month, the Special Task Force of Bihar Police shot dead a self-styled sub zonal commonder of the outlawed CPI-Maoist in Banka district.
