"A resident from Qalqilya, 21, stabbed an Israeli in the neck with a knife," in the attack in Petah Tikva, they said in a statement. "The attacker tried to flee" but was arrested by police.
The condition of the man, a 32-year-old Arab Israeli, was not believed to be life threatening. Police suggested the assailant may have thought his target was Jewish.
The attack was the latest in an uptick of violence since July 14, when three Israeli Arabs killed two Israeli security guards near the sensitive Haram al-Sharif mosque compound in Jerusalem before being shot dead.
Three Israelis were also killed last Friday when a Palestinian broke into a home in a Jewish settlement in the occupied West Bank and stabbed them.
