Personnel of the National Investigation Agency have recovered bottles with nitric and picric acids, used for making explosives, from the belongings abandoned by Yasin Bhatkal, alleged co-founder of the Indian Mujahiddin, in a room of the house at Anjuna, where he lived for four months, Goa Chief Minister Manohar Parrikar said on Wednesday.

On Saturday, an NIA team flew down to Goa with Bhatkal to ascertain his possible terror links in the State.

They returned to Delhi the same day after visiting the room he had rented at Anjuna in November 2011, and Chimbel, a slum near the city, from where one person was picked up after it emerged that he had helped Batkal get the accommodation. But he did not continue his association with him, so he was released. Bhatkal lived in the room till February 2012.
