Three more anti-police protesters being sought for allegedly assaulting a pair of New York officers on the Brooklyn Bridge have been arrested , police said Saturday . The assaults occurred one week ago when tens of thousands of demonstrators took to the streets in major cities , including New York , Washington , Boston , San Francisco and Oakland , California . In New York , two police lieutenants were monitoring a large crowd on the Brooklyn Bridge when a man attempted to hurl a garbage can on roadway , police said . The man `` violently resisted '' when the officers tried to take him into custody , with other demonstrators punching and kicking the lieutenants . The protesters also tried taking the officers ' police radios and NYPD jackets . The officers were treated for their injuries at a local hospital , police said . The protests started after a New York grand jury declined to indict a police officer in the July death of Eric Garner , who died after the Staten Island officer wrapped his arm around Garner 's neck and wrestled him to the ground . Zachary Campbell , 32 , was arrested Saturday and charged with riot , resisting arrest , obstructing government administration , said police spokeswoman Sophia Mason . Another protester , Maria Garcia , 36 , a Brooklyn resident , was arrested Friday on charges of riot , resisting arrest and obstruction of government administration , according to Mason . Jonathan Oberman , the lawyer for Garcia , told CNN affiliate WABC that Garcia was not on the bridge at the time and that police misidentified her because she is the wife of a suspect . In an email to CNN , Oberman said , `` ... our investigation into the allegations , which commenced last night , had enabled us to speak to a number of people who challenged the prosecutor 's claim that the woman pictured in the video -- relied on by the police and prosecutor as the basis of the arrest -- was Ms . Garcia . '' A third suspect , Robert Murray , 43 , also of Brooklyn , turned himself in Thursday and was charged with two counts of assault on a police officer , resisting arrest , inciting riot and obstruction of government administration , Mason said . It 's unclear whether Campbell and Murray have lawyers . A fourth suspect , Eric Linsker , 29 , who police said allegedly initiated the incident , was arrested last Saturday on charges of robbery , assaulting a police officer , riot , obstruction of governmental administration , reckless endangerment and unlawful possession of marijuana .
