The Russell Street bombing was the 27 March 1986 bombing of the Russell Street Police Headquarters complex in Melbourne, Victoria, Australia. The explosion killed Angela Rose Taylor, the first Australian policewoman to be killed in the line of duty. The materials for the bomb were stolen from Tyrconnel Mine. Several men were arrested for suspected involvement with the bombing. Stanley Taylor and Craig Minogue were convicted of murder and various other offences related to the bombing. Peter Reed and Rodney Minogue were acquitted of any offences related to the bombing, but Reed was convicted of a number of offences related to his arrest, which involved a shootout with police officers in which he and an officer were wounded. He was sentenced to 12 years' imprisonment.
