A Ceres man was arrested Friday on suspicion of possessing more than 100,000 images of child pornography, authorities said.
George Pires, 52, was taken into custody by FBI agents and Stanislaus County Sheriff's Department detectives.
The investigation began in October when deputies responded to a 911 call in the 1700 block of East Service Road. Deputies had received a tip that Pires was in possession of child porn, said Sgt. Anthony Bejaran of the Sheriff's Department.
Detectives obtained a search warrant and seized photos, videos and several computers, Bejaran said. Forensic analysis reportedly discovered thousands of images. Because of the large quantity, detectives contacted the Federal Bureau of Investigation's Sacramento Division for help in the investigation.

Pires faces federal charges of possession and manufacture of child pornography.
In addition to photos, some which were kept in binders, Bejaran said there were pornographic videos. He could not say where the photos and videos were shot, where they were obtained or Pires' specific involvement.
The voluminous amount of evidence is still being probed, Bejaran said. Detectives also are seeking the public's help to find victims.
Bejaran said Pires lived alone and was self-employed.
He said after detectives searched the home in October, they kept an eye on Pires. He said there was information that led them to believe he'd remain in the area.
On Friday, authorities showed up at the small house and made the arrest. Pires was cooperative and transported to Fresno, where his case will be heard before a federal judge.
