Nine-month-old Luka was injured on August 27 while having a picnic with his mother at a Brisbane park.
Police allege a man came up to the boy and poured a Thermos of hot coffee on the child, burning his face and chest.
Queensland Police Acting Assistant Commissioner Andrew Massingham told 4BC that regardless of the man being named in Chinese media, “the search for the person that committed that horrendous crime continues”.
He also said posts naming the alleged offender could be a “distraction to the investigation”.
“Sometimes these posts can be a distraction to what we’re attempting to achieve, but that search will continue until we locate that person,” Massingham told 4BC’s Peter Fegan on Thursday.
“Those things always need to remain confidential up until the time that we go public with the information.
“Sometimes, as I say, those sorts of things are a distraction to the investigation, but we’re very much committed to finding the individual responsible.”
He travelled by car to NSW on August 28 before flying out of Sydney airport on August 31, police said.
A warrant has been issued for his arrest.
Massingham told 4BC the alleged attack was one of the “most heinous” and “cowardly” attacks he’d seen throughout his career.
“It’s right up there – I mean we’re going to allege this individual approached that mother and child from behind, inflicting significant injuries on that child,” he said.
“That child will have those injuries for life, but certainly up there with one of the most heinous but also one of the most cowardly, I think.”
