The investigation started with a phone call into the city`s office of operational services. Someone noticed a city vehicle at a metal recycling place. Quickly after that the departments director Mike Strong called Shreveport police. Shreveport police uncovered evidence by doing surveillance at the city`s water and sewage department. Thats how Mike Strong with the city of Shreveport says they were able to determine copper and metals intended to be used for city projects were being sold for cash. "I think they were getting money for it and they were putting in their pockets." The investigation started about two to three months ago. So far eight men have been arrested in connection to the crime. Two were taken into custody late Thursday afternoon. Shreveport police say the investigation continues. They also say more arrests are expected in connection to this crime.
