The Dallas Morning News reports that a 13-year-old middle school student is accused of luring another girl her age into prostitution, police said Tuesday.

The paper says undercover officers entered the Metropolis club early Saturday, the 13-year-old victim approached an officer and made a deal to perform a sex act for money, police say. Both girls were then taken into custody.

"It's a very unusual circumstance," said Sgt. Byron Fassett, supervisor of the high-risk victims and trafficking unit. "I haven't run into a case like this."

Vice unit officers were at the club to investigate reports that alcohol was being served after-hours.

The first girl is accused of compelling prostitution, a second-degree felony that involves causing "by any means a person younger than 17 years to commit prostitution."

Police are investigating whether the girl may have persuaded other girls to engage in prostitution. She and the alleged victim attend the same school.
