Randolph woman, 60, arrested by Somerville police in prostitution sting

Police arrested a 60-year-old Randolph woman in an undercover prostitution sting last week after she allegedly offered sex for a fee via the Internet. Diane Richardson was arrested on a charge of sexual conduct for a fee Thursday at the Holiday Inn on Washington Street in Somerville. According to a police report, Somerville detectives were investigating a woman who was allegedly offering sex for a fee online and set up a meeting between an undercover police officer and the woman at the hotel. When the undercover detective went to the hotel room, police said that the woman later, identified as Richardson, answered the door and requested $125 for a half hour of sexual activity.
