Nine-year-old Eman Tanvir was found strangled at her grandmother's house in Shalimar area in Lahore, Punjab province, on June 30.
The Shalimar police said they have arrested Abdul Rehman for allegedly killing his minor sister four days ago for teasing him for having "poor handwriting", the Dawn reported.
A case of murder has been registered against unidentified killer(s).
Earlier, the police had taken victim's step-mother Saba into custody for interrogation but later released her.
He said the children had come to spend Eid holidays at their grandmother's house in Shalimar.
The SP said, in the light of investigation, that the siblings held a handwriting competition when their grandmother was not home.
Eman teased her elder brother for having poor handwriting. This annoyed the boy who allegedly put a scarf around his sister's neck and allegedly strangled her to death, he said.
Haider said the boy later also cut a vein of his arm and also locked the door of the room from inside to conceal his crime.
Giving a statement to the police, the boy said that he used to watch an Indian drama serial CID from where he had learnt the method of killing someone.
CID is an Indian detective television series in which different crime cases are investigated.
