Authorities in central Florida say two middle school girls brought knives to school, in a foiled plot to kill their classmates, cut them up and drink their blood.

Arrest affidavits released on Wednesday by the Bartow Police Department, say the two girls aged 11 and 12 were armed with knives on Tuesday this week, at Bartow Middle School before they were caught.

According to the report no one was hurt by those girls, and investigators say the girls planned to stake out a bathroom, and wait for smaller students to enter.

The affidavit says the students planned to cut their victims' throats, cut up their bodies, eat the flesh and drink their blood, and finally kill themselves.

Police say the plot was foiled when administrators searched for them, after they did not show up for classes.
