A week after the city witnessed chaotic protests marred by stone-pelting, the Kanpur Development Authority (KDA) on Saturday demolished a high-rise building owned by a close aide of the main accused in the incident, police here said.

Joint Commissioner of Police (Law and order) Anand Prakash Tiwari said that the KDA has demolished a newly-constructed building owned by one Mohammad Ishtiyaq, who is said to be a close relative of prime accused Zafar Hayat Hashmi.
