SAN ANTONIO -- Two men have been arrested in connection to young girls being sold for sex through the internet, police say.
However, only one of the men has been named by the FBI Crimes Against Children Federal Task Force.
According to San Antonio, Frank Lara was arrested on charges of sexual assault of a child.
The 40-year-old is accused of having a sexual relationship with a 16-year-old girl he met in July 2012.
The victim, who is a runaway, told officers they had sex at his home in the 2000 block of Harness Lane on several occasions from September 2012 to October 2012.
According to Lara's arrest warrant, he allowed the girl to post online advertisements from his cell phone that solicit sex in exchange for money.
Police said Lara also took lewd pictures of him and the girl having sex.
The task force, which includes detectives from the San Antonio Police Department, arranged a meeting with Lara through information on the online ad.
Investigators said they met the 16-year-old victim and a 13-year-old girl who solicited money from undercover detectives for sex.
Another man who was not named in the warrant was arrested at the scene on trafficking charges in connection to the girls.
According to the arrest warrant, the victims admitted they had been sexually assaulted by a number of people.
They were both taken to a juvenile detention center on drug charges.
