The children separately reported to two different police stations last night.
NSW Police acting assistant commissioner Paul Dunstan asked “three or four” other youngsters who were known to bepresent when the inferno was sparked to come forward with their parents to “put their side of the story”, NCA Newswire reported.
Police say the young people believed to have been involved in the fire, in a multi-level building near the Surry Hills station, did not suffer any known injuries.
Dunstan also confirmed there were up to 15 people sleeping inside the former apartment building the night before the fire, but believed they were all accounted for.
More than 120 firefighters battled the blaze at the multi-level building.
Multiple calls to emergency services were received when flames started engulfing the seven-storey building on Randle St just after 4pm, Fire and Rescue NSW said.
Firefighters from 30 fire trucks and multiple stations were involved and at least one firefighter was injured.
