Minister of Works Dave Umahi was locked inside his office by protesting workers who accuse him of highhandedness.
The minister was said to have prevented workers who came to work late from gaining access to the ministry.
The union members comprising the Housing and Works Ministry decided to lock the ministry, blocking entry and exit and preventing the minister from leaving the office.
They also claim that he stopped engineers and directors from doing their work, and has been breaking public service rules since his appointment, by bringing in consultants to run the affairs of the ministry.
He however addressed journalists and the workers after the protest.
