An underground pit suspected to be used by kidnappers was uncovered at Ile-Zik bus-stop on the Lagos/Abeokuta Expressway on Thursday.
Police were said to have uncovered human parts concealed in a pile of dirt at the site and three suspects arrested including a man posing as a destitute.
The suspects are reportedly being interrogated at a police station.
The situation caused serious traffic along the Lagos-Abeokuta expressway which is also undergoing some road rehabilitation.
Eye witnesses say that the land where the suspected kidnappers kept their victims, was fenced with barb wire.
