PLAINFIELD — The Union County Prosecutor's Office and city police are investigating a string of violent street robberies apparently victimizing lone Hispanic males, with at least four such incidents captured on surveillance video in recent weeks.

The suspects are believed to be between two and four males, using several different vehicles which authorities said were stolen, according to a release from the prosecutor's office.

Prosecutor William A. Daniel said four of the robberies happened during the weekend of Nov. 20 and 21, but that the ongoing investigation has revealed evidence which may link them to other alleged crimes dating back to the spring.
