Two Class 9 girls of Barasat Girls' High School in the district were questioned by police yesterday after their school principal allegedly found the "suicide game" in their mobile phones.
"The online game was found installed on their mobile phones. They said the game got downloaded after clicking on a link a few weeks ago. However, it's not clear what stage of the game they were in," a police officer said, adding they have taken away the phones.
Later, counsellors went to the girls' houses and spoke with them about the danger of playing the game. "They are fine now," the officer added.
West Bengal Education Minister Partha Chatterjee on Wednesday said the dangerous game should be blocked. "This is a disturbing trend. What kind of game is it? It should be immediately barred," Mr Chatterjee had said.
The police have been campaigning to tell students about the dangers of the game.
