A youth has been detained in connection with the incident.
"Four sisters aged between 4-16 years suffered burn injuries when an unidentified youth threw acid on them yesterday night at Kotmara village, 25 kms from Raigarh district headquarters, in Pusour area," Praphull Thakur, Additional Superintendent of Police said.
"They were admitted to Raigarh Metro Hospital. Three of them were stated to be out of danger," he said. The condition of the fourth girl was still critical.
The incident took place when the girls were returning from a religious discourse at night. The assailant had covered his face with a scarf.
Before the other people in the vicinity could react, he managed to escape.
Thakur said some old enmity could be the reason, and a youth had been taken into custody on suspicion and was being interrogated.
