Female students were forced to line up and take off their underwear to prove they were not on their period in a case which has outraged India.
Sixty-eight students on Thursday were made to leave their classrooms and queue up outside the restrooms, where one-by-one the women were ordered to undress.
This was after a used sanitary pad was found in a garden outside Sahjanand Girls Institute, which they are banned from during their menstrual cycle.
The women staged a protest on Monday outside the college in Bhuj saying they were forced to strip.
"There are no words to describe the humiliation that we faced," one of the students protesting told SBS News.
"The principal, Rita Raninga, abused and insulted us, asking which of us were having our periods," another student told Ahmedabad Mirror.
"Two of us who were menstruating stepped aside. Despite this, we were all taken to the washroom. There, female teachers asked us to individually remove our undergarments so they could check if we were menstruating."
The college was set up in 2012 and comes under Krantiguru Shyamji Krishna verma Kutch University. It is run by the followers of Swaminarayan Mandir, reports the Ahmedabad Mirror.
According to the sect's norms, menstruating women are not allowed to enter the temple and the kitchen and are even forbidden from touching other students. In the classroom they have to sit at the back bench.
A college administrator, P H Hirani, said the institute has a temple on campus and the girls have been instructed to follow the sect's rules.
"However, what happened to the students is unfair. Action will be taken," Hirani said.
