As Australia mourns two hostages killed in a Sydney cafe, many are wondering what Islamic gunman Man Haron Monis was doing on the streets in the first place

The Iranian-born Muslim cleric, who was killed when police commandos stormed the cafe, was on bail for around 50 counts of sexual and indecent assault and for charges of being an accessory to the murder of his ex-wife. The 31-year-old mother of two was stabbed repeatedly and set on fire with the use of lighter fluid in April 2014, allegedly by Monis' girlfriend. Monis came to the country as a refugee in 1996.
