A school principal and an attendant have been arrested in India after allegations that female students were stripped naked to check if they were menstruating after blood stains were found on a toilet wall.
The police action came after the mother of one of the "10 to 15 girls" who were put through the alleged humiliation lodged a complaint.
The incident took place on Tuesday in a village not far from Mumbai city. On Wednesday, parents protested at the school, demanding strict punishment against the authorities.
In a video, the school principal is seen arguing with angry parents - she denies that she ordered a strip-search or that it took place.
Senior police official Milind Shinde told the BBC on Thursday that they were investigating the allegations. The arrested women would be produced in court later in the day, he said.
