An Israeli man stabbed one and attacked another at Yohanani Elementary School in Herzliya after a confrontation between the three broke out on Friday, Israeli media reported.
According to the testimonies from the scene of the attack, a violent altercation broke out after the Herzliya man, who lives near the school, entered the school premises to complain about the noise.
Some students told N12 the man is familiar to them as he often complains about the noise made by children after school hours.
Two men, both fathers of students attending the Herzliya school, were summoned by their children in an attempt to remove the man from the school premises.
An aggressive confrontation quickly developed between the three, during which the suspect stabbed one of the fathers in the head, reportedly causing panic among onlooking students, teachers and parents.
The suspect was later arrested by Israel Police.
The Herzliya Municipality and its education department and professional teams have said that they would "take care of the community" in a statement released following the conclusion of the incident.
