The next day he targeted the home of a woman who was linked to the same family.

The bombing campaign generated huge concern at the time and led to a police operation to target Caswell and his associates.
Judge John Roberts, who jailed Caswell for 17 years in 2005, said: "Innocent bystanders could have been killed or mutilated by those bombs. They were offences against the community."
