AIMIM supporters on Thursday held a protest outside Parliament Street police station here after party chief Asaddudin Owaisi was named in an FIR for allegedly posting and sharing messages on social media against the maintenance of public tranquility and inciting people on divisive lines, officials said.

Over 20 people have been detained, they said.

"AIMIM supporters were protesting outside Parliament Street police station. Around 25, including two to three women, have been detained," a senior police officer said.

The Delhi Police has registered FIRs against former BJP spokespersons Nupur Sharma and Naveen Kumar Jindal, AIMIM chief Asaduddin Owaisi, controversial priest Yati Narsinghanand and others for allegedly posting and sharing messages on social media against the maintenance of public tranquility and inciting people on divisive lines, officials said on Thursday.

The FIRs were registered after an analysis of social media, they said.
