Mangaluru:  A day after a motorcycle rally of the Bharatiya Janata Yuva Morcha (BJYM) to protest the alleged killings of Hindu activists in Mangaluru and Udupi was foiled, an FIR was registered today against BJP MP Nalin Kumar Kateel, who was caught on camera purportedly threatening the police.

The video of the Dakshina Kannada district MP, in which he is purportedly seen intimidating Kadri police inspector Maruthi Nayak with shutting down Mangaluru, surfaced after several BJP leaders, including party's state unit chief B S Yeddyurappa, and hundreds of workers were detained yesterday.

Kateel was seen telling the police official that a bandh would be called if cases were registered against BJP workers who breached barricades during their "Mangaluru Chalo" bike rally.

The First Information Report (FIR) was registered against Kateel and two others under IPC section 353 (deterring public servant from discharging duty), police sources said.

The BJYM had also demanded a ban on Social Democratic Party of India, Popular Front of India and Karnataka Forum for Dignity, describing them as Muslim "radical" outfits responsible for the "unrest" in the coastal region.

Besides Yeddyurappa, other leaders, including Eshwarappa and R Ashok, were present when workers tried to push through barricades set up by the police in violation of the ban on the rally to the Deputy Commissioner's office.

The police had detained the leaders and workers to prevent their march.
