SRINAGAR: Police in Indian-administered Kashmir claimed on Tuesday they had arrested four people, including an alleged Pakistani citizen over an attack that killed five policemen.

Abdul Gani Mir, Kashmir's top law enforcement officer, said investigators had concluded that the attack was planned by LeT, a group India alleges is behind the 2008 Mumbai attacks.

“The arrested include Zubair alias Talha Zarar of Lashkar-e-Taiba who came from Multan (in Pakistan),” Inspector General of Police Mir told reporters.

Two heavily armed militants attacked a group of Central Reserve Police Force personnel in the compound of a police-run school last week, killing five of them and injuring 10 others including four civilians.

The Pakistani government rejected what it called “baseless accusations” but said India should officially share any concrete evidence.

“Such allegations and blame game will not benefit any country and will complicate the path of understanding. India should share with us any solid evidence,” foreign ministry spokesman Aizaz Ahmad Chaudhry told AFP.

In a call to local media after the assault, the deadliest attack on security forces in nearly five years, the Indian-administered Kashmir-based militant group Hizbul Mujahideen claimed responsibility.

Mir said the militants had infiltrated from the Pakistani side of the Line of Control in January and February to “cause disturbance” in Srinagar.

Three others arrested include Pradeep Singh and two “former militants”, one of whom, Bashir Ahmad Mir, was released from prison in 2008.

“They provided logistical support for the attack,” Mir said at a press conference.

India's home minister had earlier accused Pakistan of sending in the attackers but Pakistan's foreign ministry denied the charge.
