QUINCY - A Quincy man who is a Level 2 sex offender was arrested at his home by local police and FBI agents on a federal child pornography possession charge Friday morning.



Nicholas Oslander Jr., 67, was charged with one count of possession of child pornography, court records show. He was indicted by a grand jury in U.S. District Court on Thursday.



It is the second time Oslander has been federally charged with possessing child pornography. In 1999, Oslander was sentenced to 21/2 years in federal prison and three years of supervised release after pleading guilty.



At about 8 a.m. Friday, authorities armed with an arrest warrant went to 10 Edgewood Circle and took Oslander into custody without incident, FBI Boston Division spokeswoman Kristen Setera said. The street is off Russell Park, about 500 feet from Quincy High School.



On Dec. 30, 2016, Quincy police and FBI agents searched Oslander’s home, according to Quincy police logs.



Police said Oslander had images of child pornography “that involved a prepubescent minor and a minor who had not attained 12 years of age,’’ court records state.



Quincy police Capt. John Dougan confirmed the arrest Friday morning but referred all questions to the U.S. Attorney’s Office. Further information about what led to the arrest was not available Friday afternoon.



Oslander appeared in U.S. District Court on Friday afternoon. A magistrate judge ordered him held pending a detention and probable-cause hearing at 2 p.m. Tuesday.



U.S. Customs agents searched Oslander’s apartment in Quincy in 1998 as part of Operation Cathedral, one of the largest international police pornography raids ever, involving 22 states. Agents found more than 500 child pornography images on Oslander’s computer, according to court records.



In 2010, Oslander was the treasurer of the now-defunct charity Angels of Massachusetts. The charity came under fire during a Patriot Ledger investigation into where the money the group collected was going, and it was eventually shut down.



Oslander is registered as a Level 2 sex offender and was in compliance and properly classified at the time of his arrest, according to the state Sex Offender Registry Board. A Level 2 sex offender poses a ‘‘moderate’’ risk of re-offending.
