Mumbai , India ( CNN ) -- Indian police arrested a fifth suspect Sunday in the alleged gang rape of a female photographer , authorities said , in a case that has renewed outrage over safety of women in the nation . Soon after the sexual assault Thursday , police chief Satyapal Singh said they were searching for five suspects . The alleged rape of the 23-year-old woman in the financial hub of Mumbai is the latest shocking sexual assault to make headlines in the South Asian nation . The photographer and a male colleague were on assignment in the area for a print publication when some men approached them , according to Mumbai police commissioner Satypal Singh . The two had walked from a train station to a nearby mill , the woman said in a statement released by police . One of the men claimed to be a railway employee and said , `` Our boss has seen you taking photos ; you will have to come with us . '' According to the woman , he refused to let her talk to his boss , instead leading them away . Then , somewhere near the exit , one of the accused pointed at the photojournalist 's colleague , saying he was responsible for a killing a few days ago . `` I pleaded with them to let us go , but they shouted at me and threatened me , '' the woman said . She and her colleague were taken further inside the mill complex . There , they offered their camera and phone , begging to be let go . Instead , `` they tied my friend 's hands with ( a ) belt '' as two others joined the group , the woman said . `` Three people stayed with my friend , and the two took me behind a wall , '' she added . That 's where the attack allegedly occurred . The victim said her mother called her phone multiple times , before one of the men switched it off . The woman said she was threatened with , among other things , sharp pieces of a broken beer bottle . Police have since released sketches of all five suspects . The victim was in stable condition at a local hospital . The attack shocked Mumbai residents , who consider their city safer than the capital , New Delhi . According to the National Crime Records Bureau , 221 rape cases were reported in Mumbai in 2012 . Sexual harassment in India : 'The story you never wanted to hear ' But figures provided by the government show that there has been a rape reported to police every day in Mumbai between January and March . The average number of reported rapes in a month in 2013 in the city rose to 30.33 , from 19.25 in 2012 . Delhi Police said the number of reported rapes in the capital had jumped from 179 for the first 3Â½ months of last year to 463 for the same period this year . A rise in the number of rapes reported does not necessarily mean that more are being committed . It may be that recent high-profile cases have encouraged women to come forward with complaints . The case mirrors the December gang rape and death of a 23-year-old university student in the Indian capital . The victim later died at a hospital in Singapore , sparking an outcry that quickly grew to include widespread concerns about women 's safety and inequalities , triggering demonstrations in various cities . In response , the nation 's lawmakers have introduced tougher laws and punishments for sexual crimes and harassment . Despite such action , frequent episodes of sexual violence are reported in India . Across India , 24,923 cases of rape were reported last year , according to the National Crime Records Bureau . India grapples with rape and sexual violence . Journalist Dharmesh Thakkar contributed to this report from Mumbai , and CNN 's Greg Botelho contributed from Atlanta .
