SALEMBURG, N.C. —  Three men were arrested on charges that they held 10 teenagers at gunpoint and forced them to smoke marijuana and perform sex acts on one another, authorities said Tuesday.

The alleged abductors also fired four shots into the floor of the home where the teens were held early Sunday, Sampson County Sheriff Jimmy Thornton said. He described the victims as six high school-age girls and four boys and said the home belonged to one of the victims.

Three men in their 20s were arrested Sunday and charged with robbery with a dangerous weapon and second-degree kidnapping. All were held Tuesday on bonds of $500,000 or more.

No one was hurt by the gunfire, the sheriff said, but he added that the victims "were fearful for their lives."

"It's scary to think that we've got young people out there that would even think of doing something like this to someone else," Thornton said.
