Police in San Francisco arrested a 45-year-old man Thursday for allegedly attempting to have sexual contact with an underage girl.
Police had been investigating Alameda resident Emmanuel Ellison for nearly a month, after the department's Internet Crimes Against Children unit learned he had allegedly been contacting a minor through social media in an attempt to have sex with her, police said Friday.
During the investigation, officers learned Ellison had sent several sexually graphic images of himself to the girl, police said.
Officers arrested Ellison in Alameda, on suspicion of sending harmful material to a minor and arranging a meeting with a minor for sexual contact, according to police.
Ellison has been booked into San Francisco County jail.
The District Attorney's office has charged Ellison with two felony counts of sending harmful material to a minor and two misdemeanor counts of arranging to meet with a minor for sex.
