WARWICK teenager Marli Shayne Turner-Bryan has been remanded in police custody after being charged with assault occasioning bodily harm while on bail for another assault charge.

The 17-year-old was arrested on Wednesday, with police alleging she was responsible for bashing a 15-year-old girl in the early hours of Saturday morning.

The young victim was allegedly left with bruises, scratches and several lumps to her head as a result of the assault, which it is understood was retaliation for an ongoing dispute between the victim and another teen.

The teenager appeared in Warwick Magistrates Court yesterday morning - with her dreadlocks dishevelled after a night behind bars - to face the assault charge and one of breach of bail.

She allegedly offended while on bail for an assault occasioning bodily harm charge, which arose from an April incident in which she and a fellow teen allegedly bashed another girl.

Defence counsel for the teen made an application for bail on her behalf, but it was opposed by the police prosecutor and subsequently denied.

Turner-Bryan entered a plea of not guilty to both charges and her defence counsel told the court the teen "strenuously" denied any involvement in the attack.

The court heard the teenager had been staying with her grandmother in Warwick but family commitments saw that as no longer a viable option.

Although Magistrate Anne Thacker expressed her reluctance at remanding such a young person to a jail cell, she told the court at this stage Turner-Bryan was "at risk of re-offending" and ordered she be remanded in custody to re-appear in the court on Tuesday, September 13.

The teenager is also set to appear in court alongside her co-accused Tayla Michelle Farrell, 17, next month for a committal hearing related to the assault occasioning bodily harm charge.

The charges stem for an incident on April 4 of this year, where police will allege the duo attacked another teenager and at one point repeatedly stomped on her head.

As a result the teenager was taken to Warwick Hospital, where her jaw was re-wired after allegedly being split in half.

Turner-Bryan allegedly took to her Facebook page following the attack to brag about adding "another mad brawl to the collection" and declared her love for "kicking and stomping bitches".

The teenager will spend at least three nights behind bars before reappearing on the latest assault charge next week.

Both Turner-Bryan and Farrell will front the Warwick Magistrates Court to each face one charge of grievous bodily harm on October 13.
