In Haynes v Harwood [1935] 1 KB 146 the defendant left a horse unattended and untethered in a busy street. When the horse bolted, a policeman was injured in the act of bringing the horse to a halt, which he did to prevent injury occurring to other users of the street. He was able to recover damages, as the necessity of his act in affecting a ‘rescue’ was a foreseeable result of the defendant’s negligence.
