Police in Indian-administered Kashmir Tuesday said they had arrested four people including a Pakistani national from the Lashkar-e-Toiba militant group over an attack that left five policemen dead.
Abdul Gani Mir, Kashmir's top law enforcement officer, said investigators had concluded that the attack was planned by Lashkar-e-Toiba (LeT), a Pakistan-based group blamed for mass killings in Mumbai in 2008.
"The arrested include Zubair alias Talha Zarar of Lashkar-e-Toiba 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.
In a call to local media after the assault, the deadliest attack on security forces in nearly five years, the Indian Kashmir-based but pro-Pakistan militant group Hizbul Mujahideen claimed responsibility.
Mir said the militants had infiltrated from the Pakistani side of the heavily militarised informal border of Kashmir 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.
Kashmir is divided between nuclear-armed rivals India and Pakistan, with both claiming the disputed territory in its entirety.
Armed rebels have fought Indian security forces in Kashmir since 1989 for the independence of the region or its merger with Pakistan. The conflict has left tens of thousands, mostly civilians, dead so far.
India's home minister had earlier accused Pakistan of sending in the attackers but Pakistan's foreign ministry denied the charge.
