New Delhi: The investigation in a senior Jammu and Kashmir police officer case who was arrested while ferrying three terrorists out of the valley, now has been taken over by the National Investigation Agency, an official spokesman said on Saturday.

Davinder Singh, posted as the deputy superintendent of police, was arrested last weekend along with Naveed Babu, self-styled district commander of banned Hizbul Mujahideen, a new recruit Atif and an advocate Irfan Mir.

The four were caught with arms and ammunition while they were travelling in a car near Qazigund on the national highway in south Kashmir.

After receiving orders from the Union Home Ministry, the NIA has re-registered this case and started the investigation, the spokesman said.
