He added that "forensic evidence was analyzed and removed from the crime scene. The investigation is continuing."Police have heightened the security alert in the North to prevent disturbances from breaking out, Rosenfeld added.In a reaction to the attack, at around 9 a.m. 300 people marched from the village towards Rosh Pina, threw stones at police and burned tires. Police dispersed them using tear gas. "We're talking to leaders of the community in order to calm the situation," said Rosenfeld.
