NEW DELHI, India (CNN) -- At least four security officers were feared dead after a land mine blew up their cars in central India Monday, police said.
The explosion occurred in the Dhamtari district of Chhattisgarh state, said Vijay Katre, a deputy superintendent of police. Maoists were suspected in the attack.
Preliminary reports from the scene indicated that four to 10 security officers might have died, he said.
It was not immediately clear what force -- police or paramilitary -- the officers belonged to.
They were on a routine patrol when the land mine went off, Katre said.
