The National Investigation Agency (NIA) officials assisted by Jammu and Kashmir Police and Central Reserve Police Force (CRPF) conducted raids at several locations in south Kashmir's Pulwama on Wednesday.
According to reports, the NIA officials conducted searches in the house of Zahid Ahmad Wani, a militant of Jaish-e-Mohammed (JeM) at Karimabad in Pulwama.
Wani's brother Shoaib Ahmed Wani is in NIA custody in Ban Toll Palaza (Nagrota) encounter case.
Searches were also conducted at Kakpora and Drubgam area of the district, known as hotbed of militancy, sources said.
They said while NIA officials conducted searches at these locations, paramilitary CRPF men maintained tight security around the locations.
The searches were conducted nearly a month after the NIA started investigation on Nagrota encounter.
On January 31, three JeM militants from Pakistan were killed and a policeman sustained injures in an encounter after the truck they were travelling in was intercepted by police at a Ban toll plaza on Jammu-Srinagar highway.
The house of truck driver Sameer Ahmad, who was arrested, was also searched at Gundi Bagh Pulwama, sources said.
The militants were heading towards Srinagar and Police had claimed the driver captured a picture on phone and sent it to their handlers across in Pakistan.
A large quantity of arms and ammunition including wireless sets and US made M4 carbine were recovered from the site of Ban toll Plaza gunfight.
