Footy star is forced to stay behind bars after alleged Anzac Day attack that left man with 'horrific injuries'

A former Penrith Panthers junior and amateur boxer has been denied bail over an alleged assault on Anzac Day that left a man with what the court heard were horrific injuries.

Maurice Trindall, 24, appeared in Penrith Local Court on Tuesday, where he applied for bail on charges of causing grievous bodily harm with intent, wounding a person with intent to cause grievous bodily harm and affray.

Trindall, who played in the SG Ball competition for Penrith in 2018, has been held in custody since the alleged attack almost four months ago.

The court heard that Trindall, and co-accused Frederick Solo and Alexen Lyzwa, allegedly were involved in a serious assault on April 25.

Trindall was accused of allegedly throwing the initial punch, which knocked the alleged victim to the ground unconscious, where he was again attacked.

Trindall allegedly kicked the downed man while a co-accused stomped on his head, which caused 'horrific and significant injuries'. 

Magistrate George Breton described the police case as strong.

'It's an overwhelming and grave offence against someone who was unconscious in the gutter,' he said.

'It was an explosion of violence without provocation or any reasoning at all, then the good Samaritan who tried to intervene was allegedly assaulted as well.'

Barrister George Constantine said that CCTV footage of the incident showed the alleged victim 'intercepting and stopping' the car that Trindall and the co-accused had entered, 'in circumstances to continue on the agitation'.

In the argument for bail, Mr Constantine explained that Trindall's kids had medical requirements that burdened his partner.

Magistrate Breton denied bail. Trindall will remain behind bars and return to court with his co-accused on October 11.

The three accused are yet to enter pleas.
