Twenty-nine people have appeared in court as part of an inquiry into child sex abuse and neglect in Huddersfield.
The alleged offences took place in the town between 2004 and 2011 and involved girls aged between 11 and 17.
Twenty-seven men appeared before magistrates accused of offences against 18 people, including rape and trafficking. Two women are charged with child neglect.
In all the 29 defendants face a total of more than 170 charges.
Protestors shouted abuse as the defendants arrived at the town's court.
One defendant, Amere Singh Dhaliwal, 34, is charged with 54 separate counts, including 21 counts of rape.
Other charges faced by the accused include trafficking with intent to engage in sexual exploitation, sexual activity and supply of drugs.
Most of the defendants came from Huddersfield, but others came from Bradford, Dewsbury, Dudley, Manchester and Sheffield.
They appeared in groups before district Judge Michael Fanning during a lengthy court sitting and are next due to appear at Leeds Crown Court on 11 May.
I made the mistake of mocking the "Muslamic ray guns" chap years ago. What did he know? An edl, drunken northern working class chav?
And turns out he was right. Terribly sad tales of abuse that the UK ignored.
