The Delaware pediatrician who prosecutors say may have molested more than 100 patients showed a pattern of inappropriate touching that led to multiple complaints from patients and co-workers, according to court documents released this week.

But the police were unable to get enough evidence to charge him, the documents indicate.

Starting in 2005, police investigators received complaints about the pediatrician, Dr. Earl B. Bradley, of Lewes, Del., from eight patients accusing him of abuse as far back as 1999. At least one complaint was sent to a state medical group, but no action was taken to suspend Dr. Bradley’s license and he was not charged, according to the documents.

Dr. Bradley, 56, was charged in December with 32 criminal counts relating to the rapes of at least seven girls, ages 3 months to 13 years. At the time, the authorities said they had received multiple complaints about the doctor roughly a year ago.

But the new documents, which include the accounts of three doctors and a nurse, indicate that concerns were raised far earlier.
