[UPDATE BELOW] High school students in Washington Heights and Elmhurst were stabbed in unrelated incidents this morning, according to authorities. A 15-year-old is expected to survive after getting stabbed with a steak knife 16 times in his back and arm in his Upper Manhattan school, while a Queens 17-year-old was cut inside Newtown High School in a separate violent confrontation.

According to 1010WINS, cops arrested a 14-year-old suspect in the steak knife attack, which they say might be "retaliation for a bullying incident" in the School for Media and Communications at George Washington High School. The victim in the Queens stabbing is "expected to recover," and police have charged a 16-year-old student with second-degree assault and tampering, MyFoxNY reports.

The incidents come after a bloody week for New York City students in which police arrested two Independence High School kids believed to responsible for slashing a 20-year-old woman's hand and stabbing an 18-year-old man in the face and back in the Columbus Circle subway station. A 15-year-old was seriously wounded in another crime involving a knife when gang members mistook him for a Crip and sliced him from his nose to his neck on Eighth Avenue.

Update (5:08 p.m.): Another student was stabbed today, this time in Brooklyn. According to NY1, a 15-year-old student was stabbed twice in the back when he was about two blocks away from his school in East New York. A school safety officer reportedly arrested a student who was spotted dumping the weapon used in the attack. The police scanner indicates the incident took place near the corner of Liberty Avenue and Linwood Street at some time before 3 p.m.
