Twelve Bangladeshi nationals have been sued in India on charges of violation of the country's tourist visa, officials said.

They had attended a Tablighi Jamaat congregation in Delhi last month and are now in quarantine in a college in Thana Bhawan town in Uttar Pradesh's Shamli district, the state police told our New Delhi correspondent today.

Two of them tested "positive for Covid-19" on Friday evening, they said.

Indian police brought charges against them for violating the country's Foreigners Act, 1946, officials said.

With the 12 Bangladeshis, a total of 110 foreigners were blacklisted by the Indian Home Ministry for violating their tourist visa and participating in missionary activities in different parts of India after attending the Tablighi Jamaat event in Delhi.

Their visa has also been cancelled by the ministry.
