The incident took place last evening and the injured girl, a student, was admitted to a local hospital by other passengers, while the miscreants fled.
Locals alleged that police initially refused to assist the girl's relatives in taking her to the hospital.
DG (rail) Dilip Mitra said he had asked ADG (rail) to visit the spot and inquire into the delay in nabbing the culprits.
If needed assistance of the CID might be taken, he said. The girl's family alleged that the attackers had threatened the girl when she protested and resisted the eve-teasers in the crowded station.
