On Tuesday evening, a 14-year-old boy was arrested in the centre on suspicion of various offences.
He was charged with offences of assault and possession of a knife and was remanded to appear at Doncaster Magistrates Court.
A second boy, aged 15, was been arrested on Wednesday afternoon for breach of bail after being seen in the Frenchgate Centre.
Again he has been remanded and will appear at court today.
It comes after residents raised growing concerns about teenage gangs hanging around in the centre and transport interchange and causing anti-social behaviour.
There have also been reports of gangs loitering in the tunnels between the Interchange and the B&M store in Church View and police recently moved in to tackle drug dealing as well as anti-social behaviour and other crime in the area.
