A Hampshire mother who lost her son to drug addiction has urged parents to talk to their children if they suspect they are using illegal substances.
Gail Pitts made the plea as Hampshire police marked six months of Operation Fortress, which aims to make Southampton a hostile place for drug dealers.
Police have so far arrested 172 people as part of the operation and said they were making good progress.
