A girl travelling alone in an air conditioned coach of Delhi-Howrah Toofan Express train was on Tuesday found in a semi-conscious state at Madhupur in Jharkhand's Deogar district amidst suspicion that she was raped, a senior railway police official said.

Superintendent of Police (Railway) Dhanbad Division Sidho Hembram said the police suspect the girl, said to be from Azamgarh in Uttar Pradesh, was allegedly sexually assaulted in the train.

The travelling ticket examiner and the coach attendant have been detained in connection with the incident, he said and added the police were looking for two other suspects.

"She (girl) claims she has been raped but she is still in a semi-conscious state. Only after she recovers we can get a clear picture," the SP said, adding FIR has not yet been filed as the girl was not clear in her statement.

He said prima facie it seemed the girl had fled from her home.
