A 14-year-old inmate of a private hostel at Palakonda in Andhra Pradesh died of "unknown reasons" while another girl has been hospitalised in serious condition, police said.
According to the district authorities the hostel was run "illegally" and a notice has been issued to the management for violation of rules.
While Kanakala Sirisha, a class 10 student of Navodaya Model School at Palakonda, died at the government hospital on Monday night, 13-year-old Dora Umasri Vani was being admitted to Kamineni Institute of Medical Sciences (KIMS) at Srikakulam in serious condition, they said.
Sirisha belongs to Talada village in the district while Vani hails from Labhara village.
Police said a hostel warden told them that the girls were admitted to the government hospital after they complained of "abdominal pains" and were having "high fever".
According to police, Sirisha died at around 10.30 pm, while Vani was rushed to KIMS in serious condition.
Police said the management handed over Sirisha's body to her parents neither informing them nor the hospital authorities.
On receipt of information, divisional revenue officer (Palakonda) and sub-divisional police officer (SDPO) visited the hospital at Palakonda.
A case has been registered and investigations are on, police said.
Meanwhile, the school management refused to comment on the issue.
