Nooren Mohammad Khalid, who allegedly terrorised women in Colaba before he was nabbed last month, was addicted to pornographic clips, some of which were found on his phone, according to the police. Cops said that they are struggling to make a watertight case against the accused as many women who have suffered are unwilling to register complaints.

Khalid, a tailor by profession, would stalk women, masturbate at their doorstep and lock the door from outside before fleeing. Investigators said that he had committed similar offences in his hometown in Uttar Pradesh but most of them went unregistered and in a bid to keep him from running afoul of the law, his family members had sent him to Mumbai.
