A woman who demanded action against the so-called Roast Busters gang is welcoming news of arrests.
The police have arrested two 24-year-old men formerly involved in the gang, which boasted online about having sex with drunk girls, some of them underage, between 2011 and 2013.
No arrests were made at the time but police say a formal complaint this year prompted a new investigation.
In 2014, Jessie Hume delivered a petition signed by tens of thousands to Parliament in response to the lack of police action at the time.
She speaks to Susie Ferguson.
