An FIR has been registered against Samajwadi Party spokesperson Sunil Yadav Sajan for his comments allegedly targeting the Tyagi community during a TV debate, police said here on Wednesday.

In a complaint given against him on Tuesday night at the Sihani Gate police station, complainant Kameshwer Tyagi alleged that Sajan tarnished the community's image through his statement during a TV programme on politician Shrikant Tyagi.

Tyagi was Friday booked under Indian Penal Code section 354 (assault or use of criminal force on any woman) over a spat with a co-resident of the housing society.

The woman had objected to Tyagi planting some trees in the society's common area, citing violation of rules. He claimed he was within his rights to do so.

Shrikant Tyagi was arrested on Tuesday, days after he was seen in a video abusing and assaulting a woman for objecting to his alleged illegal constructions at a housing society in Noida.

the Noida Authority of the Uttar Pradesh government used a bulldozer to to remove the illegal structures outside Tyagi's ground floor apartment in Grand Omaxe society in the city's Sector 93B, as per PTI reports.

Tyagi had encroached a portion of the common area of the society in front of his flat by constructing temporary structures using pillars and tiles.

Later, charges under IPC sections 447 (criminal trespass), 323 (voluntarily causing hurt), 504 (intentional insult with intent to provoke breach of the peace) and 506 (criminal intimidation) were added against him, according to officials.

The controversial statement was allegedly given by Sajan on Monday.

According to the complaint, Sajan said the Tyagis don't pay respect to women. The complaint said Sajan said "almost all Tyagi leaders belonging to the BJP are anti-women".

Additional Superintendent of Police (First) Nipun Agarwal said legal action will be initiated against the SP spokesperson.
