The minor, identified as Ruksar, with her throat slit was found lying on a cot inside her house, they said.
Her mother is a domestic help and around 10 years ago, the victim's mother had adopted Shan Mohammad, the accused, as her son. Since then, the three had been living together, according to the police.
The police said the victim's mother has accused Mohammad, 32, of killing Ruksar.
She told the police that Mohammad is a liquor addict and often used to quarrel with her and Ruksar.
A case of murder under Section (302) of the Indian Penal Code was registered against him, Deputy Commissioner of Police (Southeast) Esha Pandey said.
On Wednesday afternoon, a PCR call was received at Sarita Vihar police station regarding murder of a girl at Janta flats. When the police reached the spot, Ruksar was found lying dead on a folding cot in the room.
"During inquiry, the victim's mother told that on Wednesday morning, she left for work as usual leaving her minor daughter and her adopted son Mohammad at home. When she returned home, she found her flat was locked from outside. She called her son on the telephone to find out about her daughter's whereabouts but he gave a suspicious response," the officer said.
