The man arrested following the death of a three-year-old boy in the foyer of a Queensland police station has been denied bail.

He faced the Southport Magistrates Court on Monday charged with an aggravated contravention of a domestic violence order and breaching bail.

Police said on the weekend the man, who cannot be named for legal reasons, was behind the wheel of a car carrying a woman and two children when it crashed into bushland at Stapylton on the Gold Coast on Saturday morning.

A witness took the woman and the three-year-old to the Beenleigh police station, while the man left the scene with a one-year-old boy before officers arrived, according to police.

Officers performed CPR on the three-year-old boy but he was not revived. 

No charges have been laid in relation to the crash or the boy’s death.

Court hears mother’s statement

The man’s defence lawyer, Shannon Fletcher, argued the case was “unusual” and he should be released because the circumstances were unlikely to be repeated.

The court heard the mother of the children had provided a statement to police accusing the man of holding a gun to her head.

“There is obviously a significantly traumatic incident that has occurred,” Ms Fletcher said.

“I would ask that your honour exercise caution in respect to that statement, noting there has obviously been a police investigation in relation to the traffic accident and there is no evidence or mention of a gun.

“That would cast some doubt on the reliability of the aggrieved in terms of allocating blame for this particular incident.

“At this stage [he] has not been charged with any wrongdoing. He accepts that he was in breach but there is dispute to the factual nature of these charges.

“His instructions are that the aggrieved was making threats towards the safety of the children and he felt obligated to enter the vehicle.”

Magistrate Gary Finger refused bail and the man did not enter a plea. 

“I have to be satisfied you won’t reoffend and I’m far from satisfied of that,” Mr Finger said.

The man will remain in custody until his next court appearance at Beenleigh next month.
