A middle school math teacher faces felony charges after threatening a student with a knife, according to police. 
 
 "Very serious, both charges are felonies, so there are some serious consequences if found guilty," said Bernalillo Police Chief Tom Romero. 
 
 The incident allegedly occurred during pop quiz at Bernalillo Middle School. Some students in class were chatting during the exam, police said. 
 
 "One of the teachers there allegedly turned around, had a knife in his hand and pointed it towards some students," said Romero. 
 
 The teacher, Benjamin Nagurski, was only about four feet away from the students, according to the police report. The knife had a wooden handle and a pointed tip. 
 
 The principal called police. 
 
 "He said he was simply removing staples from a bulletin board, and when he turned around to talk to the kids and tell them to stop talking he had the knife in his hand," said Romero. “That certainly wouldn't be the best method to remove staples.”

He bailed out of jail Monday morning with a $5,000 cash/surety bond. ||||| BERNALILLO, N.M. (AP) — A New Mexico middle school teacher is facing charges that allege he threatened a student with a knife for talking during a pop quiz, police said Monday. 
 
 Bernalillo Police Chief Tom Romero said Benjamin Nagurski was arrested Friday after school officials took him out of the classroom following the bizarre exchange. 
 
 According to a criminal complaint, the 63-year-old math teacher threatened a student with the knife and told him to stop talking to another student. 
 
 "Students interviewed later by officers all corroborated the story," said Romero, whose town is 16 miles north of Albuquerque. 
 
 The criminal complaint said that when the student confronted Nagurski about the knife, the teacher allegedly told him, "Maybe next time I'll pull a machete on you." 
 
 The complaint said Nagurski told investigators he only shook the knife in his hand and then apologized. 
 
 Nagurksi faces charges of aggravated assault with a deadly weapon and possession of an unlawful weapon. The school principal told police Nagurksi had a rounded steak knife, and another knife with a sharp tip and a wooden handle. 
 
 Nagurski was jailed on $10,000 bail. It wasn't known if he has an attorney. 
 
 Bernalillo Public Schools Superintendent Allan Tapia didn't immediately return a message seeking comment.
– Teachers don't like it when students talk during exams—but one teacher in New Mexico apparently really doesn't like it. Police say Benjamin Nagurski was arrested Friday after allegedly pulling a knife as kids chatted during a pop quiz in his math class at Bernalillo Middle School, and the police chief says the charges he faces are "very serious." Nagurski was booked on charges of aggravated assault with a deadly weapon and carrying a weapon onto school grounds, both felonies; he's currently out on bail, KOAT reports. "One of the teachers there allegedly turned around, had a knife in his hand, and pointed it toward some students" about 4 feet away, the police chief says. Students told police that Nagurski was upset with one boy in particular, telling him, "Maybe next time I'll pull a machete on you," the AP reports. But Nagurski, 63, claims he was using the knife to remove staples from a bulletin board and just happened to have it in his hand when he turned around to scold the students, the chief says, adding, "That certainly wouldn't be the best method to remove staples." The school's principal called the cops, though it's not clear how he learned of the incident.
