A man will remain behind bars after he was charged with the torture and assault of a seven-week-old baby.

Police launched an investigation after a seven-week-old boy was taken to Queensland Children’s Hospital unresponsive on March 5.

Medical examinations revealed the baby had suffered extensive injuries consistent with “prolonged and repeated physical abuse”.

The baby was removed from the care of a 27-year-old man and a 26-year-old woman.

Following a months-long investigation, the 27-year-old Forest Lake man has been charged with three counts of assault occasioning bodily harm and one count of torture.

The man, who cannot be identified, did not appear in person when his matter was mentioned at Brisbane Magistrates Court on Monday.

The matter was adjourned until June 23 for a possible bail application.

Police had earlier described the case as “deeply confronting”.

“This was a deeply confronting matter for Child Protection and Investigation Unit detectives to undertake given it involved a vulnerable infant sustaining serious injuries,” Detective Acting Senior Sergeant Joshua Brewer said.
