A 16-year-old girl was held captive for five days and raped by three boys and four men, police say.
The latest case to spark outrage in India is said to happened in a house in Ongole in the southeast of the nation.
“This is a heinous crime and we will take deterrent steps to ensure such incidents did not recur,” Andhra Pradesh state Home Minister Mekathoti Sucharitha said.
The victim, who can’t be named, was found in shock at a bus station on Saturday night and since told police she was held captive for the best part of a week.
During this time, it’s alleged the three youths and four men, all known to each other, raped her.
Now seven suspects had been arrested, four of them engineering students and, the three minors.
One of the suspects is said to have gained the girl’s trust at a bus stop on June 17 and lured her to the property.
But he lied and started the reign of abuse, police said.
Officers have helped arrange counselling for the victim.
Siddharth Kaushal, Prakasam district superintendent, said a case had been opened under the Protection of Children from Sexual Offences (POCSO) Act, and vowed that the culprits would be brought to justice.
However, it is the latest rape case to spark outrage in India recently.
Mass protests have been held after a two-year-old girl was abducted and raped beside a railway track in Delhi, and a three-year-old girl was allegedly raped by her 11-year-old neighbour in Dehradun.
The investigation in Ongole continues.
