Quentin C. Hunt is charged with burglary and theft, Old Bridge police said.

Hunt entered St. Thomas the Apostle on Route 18 around 10:45 a.m. Monday, and walked into an unoccupied classroom before leaving with the envelope, police said.

The envelope contained "miscellaneous, non-personal items," but not money, according to police. Hunt never came into contact with any students and didn't know the teacher from whom he allegedly stole, according to Capt. Steven Daroci.

Hunt was taken into custody in Elizabeth around 1 p.m. Tuesday.

In March, Hunt was arrested and charged with stealing $6,000 from a rectory safe at St. Mary's church in Lyndhurst.

St. Thomas Principal Joanne Kowit apologized for the "unfortunate" incident in a letter posted on the school's website.

"I am not trying to minimize the seriousness of this incident, but I would like you to know that at no time were your children confronted by this man or left unattended," Kowit said. "The teachers were quick to respond to the alert, sheltered in place, and kept the students calm and safe."
