PHILADELPHIA (AP) -- Four Philadelphia election workers have been charged with violating state election rules at a polling place during a special election earlier this year.

Pennsylvania Attorney General Josh Shapiro announced Monday that the workers have been charged with fraud and voter intimidation during the March 21 election for a seat in the state House of Representatives. Democrat Emilio Vazquez, a write-in candidate, won the race.

Allegations of voter fraud, electioneering and voter intimidation were reported to city and state officials during and after the election.

Shapiro says an investigation showed workers at a north Philadelphia polling place became aggressive with a voter and also told another voter that a voting machine was broken although investigators later found that it had been operational all day.

The four people charged were Dolores Shaw, judge of election; Calvin Mattox, minority inspector; Thurman George, machine inspector and Wallace Hill, bilingual translator.

Shapiro said there's no indication their actions changed the outcome of the election.
