True Blood 22 gang members and associates racked up burglary and auto theft charges in recent years as their ranks grew, making them one of the largest Hmong gangs in St. Paul.
Police knew, however, that they had a reputation for violence and carrying guns. And, in October the gang's alleged founder, Thai Yang, was arrested on suspicion of firing eight shots into a group of rivals, wounding one person in the arm.
The following month, police said, nine of the gang's alleged members and associates plied a 14-year-old girl with alcohol, dragged her into a vacant house, held her down and sexually assaulted her.
The violence drew the attention of the public and increased the information flowing to police.
"It's caused awareness," said St. Paul officer Yileng Vang, a gang investigator.
Five men and four juveniles each were charged last month in Ramsey County District Court with first-degree criminal sexual conduct, conspiracy to commit first-degree criminal sexual conduct, kidnapping and committing a crime for the benefit of a gang.
One defendant told police a similar incident had occurred at least once before.
