Indian government has detained dozens of members from an Islamic group under the pretext of anti-government measures in line with its Islamophobe policies.

Indian authorities detained scores of members of an Islamic group on Tuesday, accusing them of violence and anti-national activities.

The arrests follow a crackdown earlier this month on the Popular Front of India (PFI) in which about 100 people were detained.

The PFI has condemned the detentions and related raids as harassment and held street protests.

"This is nothing but prevention of the right to democratic protests against the central government's witch-hunt targeting PFI and is quite natural and expected under this autocratic system," PFI said on Twitter on Tuesday after what it called "massive arrests".

Police in India's most populous state of Uttar Pradesh said they detained 57 persons linked to the PFI on Tuesday because of alleged "violent acts conducted by them and their rising anti-national activities across the country".

The PFI has supported causes like street protests against a 2019 citizenship law that many Muslims see as discriminatory.

Muslims account for 13% of India's 1.4 billion people and many have complained of marginalization under the rule of Prime Minister Narendra Modi's Hindu nationalist Bhartiya Janata Party.
