In addition, violent militant elements of the anti-abortion movement have also perpetrated arson attacks and bomb threats against abortion clinics. The Auckland Medical Aid Centre experienced several arson attacks in 1976 and 1989. Lyndhurst clinic in Christchurch experienced arson attacks in May 1985 and October 1989. In 1999 Graeme White was jailed for tunneling into Lyndhurst clinic in a failed attempt to blow it up. Epsom Day clinic experienced an arson attack in 1985, a firebombing in April 1987, and a bomb threat in October 1989. These violent attacks on clinics were disavowed by anti-abortion leaders including Marilyn Pryor and Auckland SPUC president John Carroll.
