However, no replica guns or harmful elements were found in the trucks, sources said.

Driver Md Liton, helper Md Kabir and Mostafa Kamal of a truck seized with five 'replica guns' were remanded for three days yesterday.

Six other similar 'replicas' were found in a container that carried telephone accessories of Dhaka Telephone Company Limited.

Security personnel in presence of officials from Chittagong Port Authority (CPA), customs and representatives from Dhaka Telephone Company and C&F agent Emess Shipping started searching cargos loaded on 10 trucks on Tuesday.

They also searched 10 other trucks that passed out of the restricted area of the port.
