Massachusetts police are warning residents to beware of people charging exorbitant prices for snow removal services.

Senior citizens in several communities have been targeted.

The Anguses of Bedford paid almost $3,000 to have snow cleared from their roof by two men who knocked on their door.

Sara Angus tells WCVB-TV they charged $1,000 at first then came back two days later and demanded more. She says she and her husband feel like victims and called it an "expensive learning experience."

Similar scams have been reported in other towns.

Police warn homeowners to beware of people who offer to do work, yet can't produce a business card, a professional license, and drive an unmarked vehicle. Police also say agree to a price in advance and get it in writing.
