Members of the Internet Crimes Against Children Task Force arrested Phoenix Sundown, 36, in the Campo area on Tuesday afternoon, according to San Diego police.
SDPD public-affairs Lt. Scott Wahl said he could provide no further information about the case because it remained under investigation.
Sundown is accused of mailing sexually explicit materials to a girl featured on “Dance Moms,'' a Lifetime channel reality show that follows the careers of children aspiring for careers in show business and their mothers, TMZ.com reported. The child's identity has not been publicly released.
The packages arrived this week in Murrysville, Pennsylvania, where the alleged victim, who lives elsewhere, rents a post-office box, according to WPXI Channel 11 News in Pittsburgh.
Sundown was being held in San Diego Central Jail on $25,000 bail pending arraignment, scheduled for Thursday afternoon.
