Principals: Students were disciplined
Three other secondary schools have confirmed that they disciplined some of their students for their involvement in "upskirt photo" incidents.
These cases happened between 2014 and this year.
After The New Paper reported last Saturday that 30 students had been disciplined, including caning for some, for having upskirt images of six female teachers at an all-boys school, TNP received tip-offs on similar incidents in three other schools.
When contacted, the three schools - one co-ed school and two all-boys schools - confirmed the incidents.
The principal of one of the all-boys schools said: "The incident was in 2014. We spoke to the teacher and appropriate disciplinary action was taken (against) the students.
"The students have learnt their lesson and we hope all parties involved could move on."
The principal of the other all-boys school said: "There was an incident of students who were involved in taking an upskirt video of our teacher in early 2016.
"The students were disciplined and counselled and we engaged their parents to help the students learn from this incident."
The principal of the co-ed school told TNP: "The school takes a serious view of misconduct by students. The students involved in the incident in 2015 were disciplined and counselled.
"The case has been resolved and the students have apologised to the teachers and moved on."
When asked to elaborate on the incidents, all three principals said they had nothing further to add and hoped to move on from the incidents.
Taking upskirt photos or videos is included in the offences under insulting a woman's modesty.
Police figures show that there were 597 offences of insulting a woman's modesty last year, down from 634 in 2014. There have been 402 cases until September this year.
There are no official figures on upskirt incidents in schools, but psychiatrist Lim Boon Leng said it could be more common than we think.
Dr Lim, who is in private practice, told TNP: "If you look at online forums where people share upskirt photos, it's become (about) boasting rights."
Associate Professor Tan Ern Ser, a sociologist at the National University of Singapore, said: "The issue is certainly more salient these days, given the occurrences reported in the media. However, salience does not necessarily mean that it is on the rise or is more common. Nevertheless, I believe it is a cause for concern."
In response to TNP's queries, a Ministry of Education (MOE) spokesman said: "MOE and schools are committed to maintaining high standards of school discipline.
"MOE works closely with the schools and provides disciplinary guidelines which schools can take reference from to customise their school rules, based on their context and needs.
"In the management of discipline cases, schools will educate students on their wrong actions by disciplining and counselling them.
"Schools will render the necessary support to staff who are affected by the errant behaviour of the students. If a police report has been made, schools will assist the police in their investigations."
