Solicitors attempting to sell magazines to San Carlos residents, ostensibly on behalf of the charity Ronald McDonald House, are operating a scam and should be reported, according to the San Mateo County Sheriff’s Office.

The solicitors are reportedly well-dressed and very polite, according to sheriff’s Sgt. Craig Denton.

Residents who come into contact with people matching this description should call the San Mateo County Sheriff’s Office’s San Carlos bureau at 802-4277.
