Alan Anthony Dallman, 28, was arrested Sept. 2 after an investigation in connection to sexual Facebook posts aimed at minors.

Dallman was taken into custody at his home near the 2700 block of West Dorado Circle, said Deputy Alicia Cartwright of the Pima County Sheriff's Department.

Dallman was booked into the Pima County jail on suspicion of furnishing harmful items to a minor, said Cartwright.

The neighborhood is north of West Valencia Road and east of South Cardinal Avenue.

Detectives with the crimes against children unit began an investigation into Dallman after receiving information about the "disturbing and inappropriate messages directed toward minors" on Facebook, said Cartwright in a news release.

The investigation is continuing.

Authorities thanked the community for providing the information about the posts.
