MUMBAI — The police in Mumbai on Saturday arrested two more men accused of raping a photojournalist who was attacked while on assignment for an English-language magazine.

One of the five suspects in the attack was arrested on Friday, and two remained at large. The police have more than 20 teams of investigators combing the city, officials said, and Commissioner Satyapal Singh told reporters that he expected all the suspects to be in custody soon.

The attack echoed the fatal gang rape of a 23-year-old physiotherapy student in New Delhi in December and has prompted protests, as well as outrage in the Indian news media.

The 22-year-old photojournalist was assaulted by five men on Thursday night in Shakti Mills, an abandoned textile mill compound in the Lower Parel district of Mumbai, where she was taking photographs. A male colleague who had accompanied her was tied up and beaten, according to police reports.

The man arrested on Friday was identified as Chand Babu Sattar Shaikh, also known as Mohammed Abdul, an unemployed 19-year-old, the newspaper The Times of India reported. He was said to have confessed to the crime and named the other men involved. Early Saturday, the police arrested Vijay Jadhav, 19, according to a Mumbai police officer, Vinod Singh. A third suspect, Siraj Rehman Khan, was arrested Saturday evening, said Madhukar Chaudhury, an assistant police inspector.

The Hindustan Times reported that the five suspects were all unemployed men who frequented the mill area. Mr. Singh, the police commissioner, said two of them had criminal records.

“This is a very, very serious matter,” Mr. Singh said, adding, “We will do our best to collect all scientific evidence to ensure that this is a foolproof case and that the culprits get maximum punishment.”

Speaking to the Indian television news channel IBNLive, a grandmother of one of the suspects said that her grandson, who is a minor, was not present at the time of the assault.

The episode has reignited debate in Parliament over violence against women in India.

“This country cannot afford to have our women and children insecure in the hands of those who attack them,” Law Minister Kapil Sibal told reporters on Friday.
