Bangalore : A 30-year-old skating instructor was arrested on Sunday on the charge of raping a six-year-old girl student at Vibgyor High, Marathahalli.

The suspect, Mustafa alias Munna, is a native of Darbhanga in Bihar and the father of a five-year-old girl. He has been working in Vibgyor High since 2011.

The police seized a laptop and a mobile phone from him. The laptop contained “incriminating pornographic videos of schoolgirls being raped, which he had downloaded from the Internet,” Bangalore Police Commissioner Raghavendra H Auradkar told the media at a hurriedly convened press conference at HAL police station.

The police said Mustafa is a pervert who derives pleasure from watching videos of schoolgirls being raped.

He had been showing such video clips and nude pictures to girl students at Vibgyor High as well as at another school in Whitefield where he was employed earlier.

Mustafa was also in the habit of clicking nude pictures of schoolgirls.

Auradkar did not give details of the incident that took place on July 2.

However, he said: “There are complaints that he was involved in several such cases in another school as well. The police believe they could be genuine as they are oral complaints received from highly reliable sources.”

To a query, Auradkar said: “I don’t think the school management verified his antecedents before appointing him.”

Joint Commissioner of Police (Law and Order-East) K V Sharathchandra said it was basic policing that helped arrest Mustafa. The police zeroed in on him based on some clues.

The suspicion strengthened after the police found pornographic content on his laptop. On interrogation, he admitted to raping the minor.

Mustafa did not destroy the evidence and presumed his act would go unnoticed. It is not known if he wanted to experiment the “acts in the video clips that he downloaded from the Internet”, Sharathchandra said.

The police said they believe another school staff is also involved in the incident and he would be arrested soon. Mustafa has been booked under IPC Section 376 (rape) and Sections 4 and 6 of POCSO Act, 2012. He was arrested from his house on Ramakrishna Road in Varthur.

Mustafa’s father Murthuja is a car driver and mother, a maid servant. They moved to Bangalore about 20 years ago to eke out a living.

Mustafa completed schooling in Bangalore and did his BPEd from a private college in Raichur.

Police said they will produce him before the court and seek his custody as they need to continue the investigation. He will also be subjected to a medical examination.

Auradkar said Mustafa was drawing a salary of Rs 18,000 per month. But he owned three expensive laptops and a mobile phone.

The police will also probe how he managed to buy such expensive gadgets.
