Bangalore, July 20 (IANS) Musthafa, a 30-year-old skating instructor at a private school here, was arrested late Sunday on charges of sexually assaulting a six-year-old student in a classroom three weeks ago that rocked this city and outraged hundreds of parents.

"The accused has been arrested under sections 376 and 406 of the Indian Penal Code (IPC) after he was interrogated with six other staff members of the school following a complaint by the victim's parents July 14," Commissioner of Police Raghavendra Auradkar told reporters here.

Police also seized from the accused a mobile handset and a laptop, which contained incriminating pornographic videos showing school children being raped.

"That shows the state of his perverted mind. The videos were downloaded from porn sites through internet. Though the accused has been living in the city for over the last 20 years, he hails from Darbhanga in Bihar," the police chief said.

Musthafa alias Munna has been working in the school (Vibgyor High) in the city's upscale southeast suburb since 2011, drawing a salary of Rs.18,000 per month.

"He is married and has a three-year-old child. We will produce him in court Monday and seek his custody for further interrogation and investigation," Auradkar said.

Preliminary interrogation revealed that the accused was thrown out of a previous school following a similar complaint though no case was registered against him then.

"The heinous crime has created a lot of anguish among the parents and in the society. We have been able to achieve the breakthrough after sustained interrogation and investigation by senior police officers during the last five-six days," Auradkar said.

Though the horrifying incident took place July 2, the case was registered July 14 in a police station by the girl's parents when she complained about the injury on her body following the sexual assault.
