A shocking incident of a Class VII girl allegedly stabbing a Class 1 boy in a private school in Lucknow, Uttar Pradesh, has led other prominent schools in the city to check the school bags of students, and what they discovered will leave you stunned.

Over two dozen schools carried out random checks of students' bags and found items like cigarettes to a porn magazine to razors and trimmers.

"We were shocked to find that students of Class 9 bring a pornography magazine with a brown cover and a label of science subject. We also found packets of cigarette and lighters from bags of several boys. These things have been confiscated and notices issued to their parents," Hindustan Times quoted a teacher of an all-boys educational institution as saying.

The teacher also said the authorities found razors, shaving foam and trimmers in the bags of some schoolboys.

"When confronted, they said their parents do not allow them to shave at home so they bring such items to school and use them before leaving for home," another teacher, on condition of anonymity, told the publication.

The bags were also checked in an all-girls school just before the interval and the authorities discovered scissors, blade, nail polish, lipsticks and perfume, among other items.

"Many of them had brought iPods and mobile phones, too. They have been seized," a teacher said.

Several schools have banned students from bringing mobile phones to classrooms, but the surprise check revealed students hide their phones in bags and diaries. The principal of a school affiliated with the CBSE board insisted that parents need to check the bags of their children before sending them to school.

"One of the students had brought a mobile phone hidden in a school diary, assuming that it won't come under the teachers' scanner. We have informed his parents about it," the principal of a co-educational school said.
