WORCESTER, Mass. (AP) — Four Massachusetts residents have been charged with keeping a 16-year-old girl in a basement that a police officer described as a “torture chamber.”

Police say the teenager was sexually assaulted, had her hair shaved off and was burned with a cigarette.

The suspects are charged with kidnapping and other offenses. They appeared in a hearing Wednesday to determine whether they can be held without bail.

Prosecutors say the suspects held the girl in an Auburn home because they thought she knew who was responsible for a Dec. 27 home invasion. Prosecutors say she was duct-taped to a chair and had a machete held against her throat.
