MEDFORD, MA — A pair of poll workers were arrested Tuesday after being told to leave for "unprofessional" behavior and assaulting a police officer and colleague, according to the City Clerk's office. Heather Bourque, 34, of Wilmington, and Derek Sands, 34, of Chelsea, were scheduled to work at the Gantcher Center at 7 a.m. Tuesday, police said.

They arrived half an hour late and were seen "nodding off" and not performing their duties, according to police. They were "hugging and holding each other" and "very rude" to voters, police said.

Sands and Bourque were ordered to leave after they were separated and warned about their behavior. Sands was disruptive and caused voters to leave the polling place, police said. An officer working the polls tried to arrest Sands, but Bourque jumped on his back, police said. Another poll worker was assaulted during the struggle, according to City Clerk Adam Hurtubise.
