Abstract : Massive gas outflows are considered a key component in the process of galaxy formation and evolution. I will present recent results obtained from HI and CO observations of a number of objects where the radio jet is playing a major role in producing large and fast gas outflows. The results are reinforcing the conclusion that gas outflows have a complex and multiphase structure and that cold gas in different phases (atomic and molecular) represents a major component. High-spatial resolution observations have allowed, in a number of sources, to locate the region where the outflow originates as well as to derive more accurate estimates of the mass outflow rate and the associated energy. Therefore, these results provide important constraints for understanding the mechanisms that lie at the origin of the outflows. A possible link between the evolutionary stage of the radio source and the presence of outflow will also be discussed.
