Four detonators, six gelatin sticks and some wires were recovered yesterday from Painthal nullah (stream) in Katra, the base camp of Shri Mata Vaishno Devi Shrine Board (SMVDSB), a police officer said.
The official noted that the explosives might have been used by a nearby mining factory in the area and washed away in the stream.
A case has been registered in the matter and the probe is on, police said.
