MUMBAI - 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 Mohammad.

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

In the video, available on social media, Singh, and in an apparent reference to the Muslim prophet, said an elderly man had married a girl decades his junior

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