New Delhi: Aam Aadmi Party on Friday launched a vitriolic attack on Delhi police, saying they were planning to book AAP MLA Surinder Singh, who has been charged with assaulting an NDMC worker, under stringent sections at the behest of a former MLA.

The party also claimed that police was reluctant to file an FIR against the NDMC officials, who were found extorting money from a vendor, in whose support Singh had come.
