A criminal investigation will apparently be opened against Arab MK Muhammed Kenaan for punching and cursing a policeman this morning. Kenaan was part of a Knesset group visiting the Interior Ministry office in eastern Jerusalem this morning. An argument developed between the security guard and the MK, at which point Kenaan allegedly directed particularly strong curses against the policeman on duty. When the latter said that he could arrest Kenaan for insulting a public servant, the MK pushed and then punched the policeman in the face, who required hospital care for dizziness and related problems. Kenaan himself later said that he merely attempted to extricate himself from the clutches of the policeman when he informed him that he [Kenaan] was under arrest, and that the policeman must learn to act in a more cultured manner.
