The opposition National Democratic Congress seems to have discovered another vigilante group doing the bidding of the ruling New Patriotic Party (NPP). Aside the known ones such as the Invisible Forces, Delta Forces and Bolga Bull Dogs, the NDC mentions the Volta Crocodiles in its latest list of the pro-NPP vigilante groups. At a meeting with journalists at its headquarters in Accra on Thursday, National Chairman Kofi Portuphy said the Volta Crocodiles are part of the vigilante groups terrorizing Ghanaians.
