BEDFORD - Police are warning of a telephone scam in which callers posing as Bedford first responders try to solicit donations.

Police said the callers say they are representing Bedford firefighters. However, the Bedford Firefighters Association does not do phone soliciting, police said. Funds are raised through boot drives, golf tournaments and by letters, police said, but not by telephone.

Other organizations, including the Professional Firefighters of New Hampshire and the Bedford Police Union, will raise funds through phone calls, but neither is doing so now in Bedford, police said.
