A case was registered by the city police on Sunday against the three individuals, who had gone to La Martiniere School last week claiming to represent the Ministry of Human Resource Development as a probe panel to investigate the incident of a student allegedly driven to suicide after being caned at the school.

The Kolkata Police received a complaint from the Ministry about the three persons.

Emblems Act violated

They had violated the rules of the Emblems and Names (Prevention of Improper Use) Act, 1950 as they had used the emblem of the Ashoka Pillar, on their visiting cards, without being authorised to do so, Damayanti Sen, a senior official of the city police, said.

“They have been charged under section 419 of the Indian Penal Code and the relevant sections of the Emblems and Names Act,” Ms. Sen said adding that since section 419 was a cognisable offence, they may be arrested.

Report sought

On Wednesday, Ramesh Bhattacharjee, Dr. Dilip Dutta and Antony Arun Biswas visited the school and asked the authorities to submit a report on the incident of the student's suicide and the action taken by the authorities so far.

Initially, Mr. Bhattacharjee had claimed to be a member of the Secondary and Higher Education Department of the Ministry.

When Ministry denied that it had authorised any such probe, he changed his stand and claimed to be a member of the Rashtriya Sanskrit Parishad, an advisory body of the Ministry.

Dr. Dutta is a former official of the State's School Education Department and Mr. Biswas is the president of the All India Minorities and Weaker Sections Council.
