The accused, who failed to produce valid documents for transporting the items, was arrested in Pallel area, police said.
Police seized from him four plastic sacks containing 72,000 peacock feather shafts weighing approximately 142 kg, and a vehicle.
Investigation is underway to find out from where the peacock feather shafts were procured, as the bird is hardly found in Manipur.
