A woman passenger onboard a Delhi-bound train was detained at Tatanagar railway station here after Railway Protection Force seized exotic breeds of poisonous snakes, lizards and insects from her possession, an RPF official said on Monday.

Acting on a rip-off, the RPF personnel conducted a search in the general compartment of Delhi-bound Neelanchal Express on Sunday night and seized the snakes, lizards and insects stuffed in plastic bags.
