Five Massachusetts college students appeared in court Thursday, accused of plotting to lure a man to their campus through a dating app and then seizing him as part of a “Catch a Predator” trend on TikTok.

The Assumption University students, all teenagers, were arraigned on conspiracy and kidnapping charges. Not-guilty pleas were entered for all of them, and they are due back in Worcester District Court on March 28 for a pre-trial conference.

The defendants — Kelsy Brainard, 18; Easton Randall, 19; Kevin Carroll, 18; Isabella Trudeau, 18; and Joaquin Smith, 18 — stood stone-faced in court, showing little emotion and addressing a judge only through attorneys. A sixth defendant was being arraigned separately in juvenile court.

Police said Brainard’s Tinder account was used to lure the man to the private, Roman Catholic school in Worcester. She faces an additional charge of witness intimidation. A male student in the group also faces a charge of assault and battery with a dangerous weapon.
