Police Detonate 'Mother Of Satan' Explosive At Suburban Home

UPDATE: Two explosions have been heard.

Emergency services earlier set up a 100-metre exclusion zone around a north Adelaide home as they prepared to detonate an explosive device allegedly found inside the property on Monday night.

Police prosecutors allege a 43-year-old man, arrested and charged at the property last night, mixed chemicals into a substance referred to as 'Mother of Satan'.

The substance is highly volatile, a court has heard.

Because it cannot be transported it needs to be detonated by authorities at the scene.

An explosive device was detonated on Tuesday afternoon, with a second explosion occurring about 45 minutes later.

At least one device was allegedly located inside a garden shed at the Davoren Park property.

Police allege the substance had the potential to cause "substantial damage and injury" if it had not been discovered in time.

However, South Australia police are continuing to insist there is no danger or threat to the public but nearby residents have been evacuated for their safety.

By early Tuesday afternoon, decontamination pods were seen arriving at the scene, after experts spent the night assessing the alleged explosive devices.

South Australia police said they were called to the home just after 8:30pm on Monday after receiving "fresh information" about a potentially explosive device inside the property.

Prosecutors have told a magistrates court police first attended the property in February, after they received reports of a Facebook post from the accused Aaron Ellis, claiming he "hated Muslims."

Police said they found nothing that constituted an offence at the time.

After attending the property on Monday, they arrested Ellis and charged him with possessing and manufacturing explosives.

He appeared before Elizabeth Magistrates Court on Tuesday where he was refused bail.

A court heard he is refusing to speak to police.

A Facebook post seen by 10 daily, believed to be from the now-removed Facebook page of the accused, shows an anti-Muslim message that was shared by Ellis in March -- a month after police first attended his home.

The post describes all Muslims as "waiting for anti christ to slaughter jews and christians" and "wanting a caliphate".

On Tuesday, police also seized what appears to be chemicals and explosives from the home.
