As the race to piece together the profiles of father and son terrorists Sajid and Naveed Akram stretches across three countries, family members in India have gone to ground, neighbours are lying low and a misinformation campaign is raging online.

Sajid and his son, Naveed, 24, are suspected of having carried out the attack during a Hanukkah celebration on Sunday, killing 15 people and leaving dozens of others injured.

Sajid, an Indian passport holder, moved to Australia in search of employment after completing his bachelor’s degree and had been living in Australia since 1998, while his son was born there.
