An attempted-robbery suspect who got into a violent confrontation with a police officer Saturday morning in West Philadelphia — allegedly beating the cop with the cop’s baton before the officer shot and injured him — was identified Sunday as Sidney Clayton, 31, of 34th Street near Haverford Avenue in Mantua. Police Lt. Ray Evers said Clayton, who is at the Hospital of the University of Pennsylvania in critical but stable condition, was charged with attempted murder, aggravated assault, possession of an instrument of crime and related offenses.
