UPDATED, Aug. 3: A 22-year-old East Arlington man was arraigned Friday, July 31, on child-pornography charges after his arrest by town police and federal agents.

Antonio Gutierrez was arrested Thursday, July 30, a police spokesman said the next in a news release. At his appearance, in the John Joseph Moakley U.S. Courthouse in Boston, on federal charges of receiving and possessing child pornography, Gutierrez learned that he faces an endangerment hearing, set for 3 p.m. Wednesday, Aug. 5. 

Investigators obtained a warrant for a residence on Spring Road in Arlington, which is also the location of a residential day-care program owned by the suspect's extended family. However, spokesman John Guilfoil said that when officers and FBI agents went to the residence, it was determined that Gutierrez no longer lived there. A preliminary investigation indicates that the alleged actions of the suspect did not include the daycare or its children.

The investigation led authorities to Gutierrez's home on Melrose Street. The suspect was questioned, and investigators seized computer equipment from his home.

"I am grateful that this individual has been taken into custody and will answer for his alleged crimes," Chief Fred Ryan said in the release. "We strongly value our partnership and close working relationship with the FBI, and the communication and sharing of resources between our two agencies."

The U.S. attorney's office has been asked to provide information about how he pleaded at the arraignment.
