Police in Upper Darby, Pennsylvania accused an 18-year-old native of Ecuador of raping a 5-year-old relative and causing her to contract chlamydia, WCAU-TV reported.
"I guess the best way for me to describe this guy is an animal," superintendent Michael Chitwood said of the suspect, identified by the Philadelphia Inquirer as Luis Arevelo.
The attack allegedly happened months ago, but the victim's illness was not discovered until her mother took her to a Philadelphia hospital on Tuesday. The girl's mother also reportedly told authorities that she had been told about the attack.
Arevelo was charged with endangering the welfare of a child, indecent sexual assault, and rape of a child. He allegedly admitted to police that he has chlamydia, while denying that he attacked the girl. He is currently being held on a $250,000 cash bond.
Chitwood also said that the suspect, who is residing in the U.S. legally, asked to be tried in his native country.
"My statement to detectives was, 'If they want to come and fly him out, that's good with me,'" he told reporters.
