This was contained in a statement signed by the corps spokesperson, Olusola Odumosu, on Monday.
According to the statement, the suspects were arrested following credible information and surveillance mounted by the Directorate of Intelligence and Investigation Crack Squad from the NSCDC National Headquarters with the support of other stakeholders.
The corps revealed that five inches galvanised pipes (5 mm), angle irons and a hand saw which was used in carrying out the destruction were recovered from the suspects.
It was uncovered that most of the suspects were artisans whose activities are domiciled around the crime scene which is located close to the headquarters of Federal Mortgage Bank, Central Business District, Abuja.
The arrested suspects were Abdullahi Bello, 18, Suleja LGA, Niger State, Julius David Madaki, 18, Sanga LGA, Kaduna State, Gambo Clement, 18, Sanga LGA, Kaduna State, Sadiq Abdullahi, 24, Billiri LGA, Gombe State and Abdulaziz Aliyu 25, Sanga LGA Kaduna State.
The corps noted that a discreet investigation into the matter had commenced and would be followed by diligent prosecution of the suspects.
It therefore warned vandals of bridges to desist from this nefarious act of vandalising galvanised pipes and aluminium used in the construction and reinforcement of bridges or risk arrest and possible jail terms as security is beefed up around those public utilities by the eagle-eyed operatives of the corps.
