Srinagar: Violent protests broke out in the state capital after separatist leader Masarat Alam was arrested by the Jammu and Kashmir Police on Friday.

Commenting on the developments in the Valley today, Home Minister Rajnath Singh said there would be no compromise in matters of national security. "The state government will take whatever is required in the interest of the nation," he said and added that those indulging in anti-national activities will not be spared.

The J&K Police had to use tear gas and resort to lathicharge to disperse the crowd, which was heading for a march in Tral town of Pulwama district.

Under pressure from the Centre, the J&K Police arrested Alam, ahead of his rally in Tral this morning.

The 45-year-old hardline separatist leader was arrested for having allegedly waved a Pakistani flag to greet Hurriyat hardliner Syed Ali Shah Geelani during a rally in Srinagar some days back.

"Alam has been arrested in the case, registered in Budgam ​police station in connection with the provocative actions during the rally on Wednesday," a senior police officer said.

Police have imposed Section 13A(unlawful activities), 120B (criminal conspiracy), 147 (riots), 427 (damage to public property) under CrPC on Alam.

The arrest comes a day after Alam and Geelani were placed under house arrest to prevent them from leading the rally in Tral.

Earlier today, Alam said that the J&K government doesn't want the rally to be successful and that is why such an action has been taken. The separatist leader opined that the administration should follow the Hurriyat program.

“Let the government do whatever it wants to, the people are being stopped for attending that rally, but they will attend,” Alam said.

Reacting to Alam's arrest, BJP leader Siddharth Anand Singh justified J&K government’s move and said that nobody can raise pro-Pakistan slogans or waive Pakistan flags.

He further said that the government will continue to function keeping the national interest at the forefront.

Deputy Chief Minister Nirmal Singh today said the state government will act tough against them and not tolerate their 'provocative' actions in J&K again.

"We will act again, if any such incident (of provocative activities and hoisting Pakistani flag) is repeated. We are not going to tolerate it," Singh told reporters here today.

"Jammu and Kashmir government has taken the cognizance, it’s capable of taking appropriate actions and is doing so," he added.

Union Minister Jitendra Singh and BJP leader said the action has been taken in accordance with the law. Alam has been arrested to uphold national interest and there will be no compromise on this front, Singh asserted.

"As far as the BJP leadership is concerned, both at the centre as well as the state, our stand has been very consistent as far as nationalism is concerned, patriotism is concerned and we follow a principle of zero-tolerance towards the terrorism and towards separatism," Singh told ANI.

The People's Democratic Party (PDP) said Alam had been arrested under procedure and not due to the pressure reportedly brought on it by Union Home Minister Rajnath Singh or Chief Minister Mufti Mohammad Sayeed.

Moderate Hurriyat leader Mirwaiz Umar Farooq accused the army of killing youths after labelling them terrorists. "There is no arrest, no FIR. The government has to put an end to state terrorism," he said.

Meanwhile, Congress leader Digvijay Singh took to his Twitter account and wrote: “Want to know under what sections Alam and Geelani have been arrested.”

During Wednesday's rally in Srinagar, Alam, released from jail last month, had praised founder of Lashker-e-Toiba terror outfit Hafiz Mohammed Sayeed and asked people to join hands with his outfit.

Alam was part of a procession that gathered in uptown Hyderpora locality of Srinagar city to welcome Geelani who returned to the Valley on Wednesday after remaining in New Delhi during winter for health reasons. Alam was flanked by youth, who raised pro-Pakistan and pro-freedom slogans and displayed Pakistan flags.

The police have registered an FIR against Geelani, Alam and another separatist leader from Hurriyat Conference under various sections of Ranbir Penal Code and Unlawful (Activities) Prevention Act.

"Geelani has been placed under house arrest. A posse of policemen has been deployed outside the Hurriyat chairman's house at Hyderpora as a preventive measure to maintain law and order," a police officer said, adding that similar restriction has been slapped on Alam.

Mirwaiz Umar Farooq of the moderate Hurriyat Conference will also be not allowed to proceed towards Tral, police sources said. It was not clear whether he has also been placed under house arrest.

The government of Chief Minister Mufti Mohammed Sayeed has already denied permission to separatists for Friday's rally in Tral town of Pulwama district.

Sayeed on Thursday said that waving of Pakistani flags and raising pro-Pak slogans were "not acceptable" and "will not be tolerated". The remarks came after the CM came under attack from all quarters including ally BJP for allowing hardline Hurriyat leader Geelani to hold a rally in Srinagar on Wednesday where pro-Pakistan slogans were shouted and Pakistani flags waved.

In view of the development, Sayeed had asked police to deny permission for Friday's rally which was scheduled to be taken from Srinagar to Tral where a youth was killed allegedly by the Army while in their custody.

The police is also likely to enforce prohibitory orders under Section 144 to restrict movement of people.

Geelani issued a statement late in the evening saying that he would not be cowed down by the state government.

Hours after the rally in Srinagar on Wednesday, Sayeed was called by Home Minister Rajnath Singh who asked him to take "immediate and stringent" action against the law breakers.

Sayeed's decision to release Alam had attracted a lot of flak both from the opposition and his ruling ally Bharatiya Janata Party.

The development even rocked the Parliament in New Delhi where the union Home Minister Rajnath Singh had to make a statement to cool tempers over the top separatist leader's release.
