Two more New England College students have been arrested on hazing charges linked to a pledging ceremony last fall.

Henniker police say 25-year-old Nicholas Weiss and 22-year-old Kevin Phelps used a World War II-era bayonet, which wasn't connected to a rifle, to brand at least seven students during the pledging ceremony at the Sigma Alpha Beta fraternity.

The Concord Monitor reports they were each charged with four misdemeanor counts of student hazing related to the Oct. 25 incident. Seven students were arrested in March.

Police started investigating after several pledges admitted themselves to the infirmary with severe burn-related injuries.
