The women, in their complaint, had alleged that the sub-inspector thrashed them inside the police station yesterday, forcing them to confess in a case of robbery.
Four police personnel, including the sub-inspector who had allegedly beaten the two women, were today suspended, Delhi Police spokesperson Rajan Bhagat told PTI.
The women were yesterday taken to Ambedkar Hospital for treatment where a large number of locals created ruckus over the alleged custodial brutality.
An FIR has been registered in this regard under sections 323 (voluntarily causing hurt), 330 (voluntarily causing hurt to extort confession), 342 (wrongful confinement), 509 (word, gesture or act intended to insult the modesty of a woman) of the IPC and under the SC Act, Bhagat said.
A departmental enquiry has been initiated in this connection and investigation is underway, he said.
