Photo / John McCombe "Appalling," says Christchurch developer David Henderson of personal details about marital breakdown, health, fitness, weight loss and pictures of family, friends and pets being passed by police to a liquidator. Henderson was commenting after a new Court of Appeal case brought by business associate Ian Bruce Hyndman against the liquidator Robert Bruce Walker. The appeal court decision referred to Henderson's involvement with Hyndman and a tape drive which had Henderson's personal information on it and which Walker was permitted to retain after police seized it by executing search warrants.
