A 45-year-old Colorado Springs man faces sexual assault charges after a month long Internet crimes investigation.
Colorado Springs Police arrested Timothy Whalen.
Detectives say he was having an online relationship with a 14 year old girl, even buying gifts for her, and taking her out several times.
Police say Whalen also had sexual contact with the 14-year old.
Police got involved when they say the girl's father found sexually explicit emails.
