A second man was arrested in the gang rape of a photojournalist in Mumbai, police said on Saturday, promising swift justice for a crime that has renewed public outcry over sexual violence in India. The 22-year-old Indian woman was in stable condition, after being repeatedly raped by up to five suspects on Thursday night in a deserted textile mill in an isolated and decrepit corner of India’s financial capital. She and a male colleague, who was tied up and beaten during the attack, had been on a magazine assignment to take photographs of the neighbourhood. Police said the suspects had approached the journalists on the pretense of helping them get permission to shoot inside the crumbling building. Police arrested the second suspect before dawn on Saturday, and units from India’s elite crime branch were hunting three more suspects. The first man arrested on Friday, an unemployed 19-year-old from south Mumbai, had identified the other four, police said. The attack incensed many in India already sickened by sexual violence after the deadly gang rape of a student on a bus in New Delhi in December raised alarms about women’s safety and revealed a culture in which rape victims are often pressed by social pressure or police into keeping silent. Pledging to crack down, the federal government recently created fast-track courts, increased prison terms for rape and criminalized voyeurism, stalking, acid attacks and the trafficking of women.
