The man accused of setting fire to his Rozelle shop to claim insurance money has been charged with extra offences over the explosion, which killed three people.

Adeel Ahmad Khan, 45, already charged with three counts of murder, two of attempted murder, three of manslaughter and 17 charges relating to the damage to property caused by the fire, is now facing four extra charges of reckless damage.

Adeel Khan has been additionally charged with reckless damage.

Mr Khan, who was injured in the fire and has been too ill to face court previously, appeared via audio-visual link in Central Local Court on Tuesday to hear the new charges, which relate to the damage of surrounding units and shops.

Wearing prison greens, Mr Khan only spoke to indicate he could hear the proceedings and to say "good morning".
