The minor's parents have lodged a complaint alleging that the elderly teacher had touched her private parts.
The police arrested the accused on Tuesday, but refused to share any details about the incident until the investigation continues.
“The teacher is a friend of the school principal and had started working post retirement,” Ramanagara Superintendent of Police Anupam Agarwal said.
Agarwal further said that on getting to know about the incident, parents approached the school today but the principal refused to co-operate after which they informed the police.
Later, police arrested both the teacher and the principal of the school.
A case has been booked under Section 8 (Sexual Assault) and 21 (relating to failure to report the offence) under the Protection of Children from Sexual Offences Act (POCSO), he said, PTI reported.
Today's heinous incident came to light days after a seven-year-old school girl was allegedly raped her by the son of the attendant of the school. The 28-year-old accused was later arrested in the case.
The incident was reported on July 21. The mother of the victim had filed the complaint. The seven-year-old is a class II student.
And last month, a six-year-old girl of class I, was raped in the city's reputed Vibgyor School, triggering fierce protests by parents.
The school re-opened after 10 days after it was shut over the outrageous incident that led to severe public protests and prompted police to issue tough guidelines for children's safety.
Two gymnastics instructors have been arrested in connection with this case.
Meanwhile, expressing deep concern over the alleged rape case in the Vibgyor School, the Union Human Resource Development Ministry today sought a detailed report from Council of Indian School Certificate Examination (CISCE).
The ministry also reminded the CISCE that Karnataka government had recommended that it withdraw the affiliation given to Vibgyor High School, where the minor was allegedly raped, and asked what action it had taken.
"The ministry has felt that safety and security of school children in any school system is a critical priority. It is deeply disturbing that such a serious incident has happened. It has also noted the reports of other incidents in some other schools affiliated with the CISCE," it said in a statement.
Citing its various guidelines and laws, the HRD ministry has highlighted the role of the school in the entire matter.
