I am the father of a teenage son who was acting strange and I knew he was stealing things from the house. I contacted Q investigations and they agreed to follow him for 4 hours which was enough to prove what I suspected, he was buying drugs from his friend. The photographs taken by Q investigations were enough to break up the arrangement and I informed the dealer that I would give them to the police if he had any more contact with my son. It cost me £200 but it was money well spent. David W.
