Indian police detained a state lawmaker from Prime Minister Narendra Modi’s party on Tuesday on suspicion of “promoting enmity in the name of religion” after Muslim groups demanded his arrest for his comments about the Prophet Muhammad (PBUH).

The detention of T Raja Singh, a lawmaker in the southern state of Telangana, comes months after his Bharatiya Janata Party (BJP) suspended spokesperson Nupur Sharma for her remarks that had led to a diplomatic backlash against India.

“He has been charged with promoting enmity in the name of religion,” Joel Davis, a senior police official in Hyderabad city, told Reuters.

“We have detained him and we will arrest him. This is about the recent video that he posted.”

In the video, available on social media, Singh, in an apparent reference to the Prophet, made controversial remarks.

Singh could not be reached for comment.

The Hindu nationalist BJP would examine Singh’s remarks and take action if he was found to have violated its code, party spokesperson K. Krishna Rao told the News18 channel.

Hundreds of Muslims protested against Singh on Monday evening after the video appeared on social media, footage from media showed.
