Delp reportedly struck a woman and her male friend during an argument in June, leaving the male victim "bleeding heavily" by the time authorities arrived, according to a police report obtained by TMZ.
His girlfriend and Teen Mom 2 co-star Jenelle Evans is believed to have been present at the time of the incident.
Delp apparently turned himself in one week after the altercation and was booked on two counts of simple assault.
He has been ordered to appear in court on August 31 to face the charges.
Delp's girlfriend Evans has denied that he committed any wrongdoing, writing on Twitter that the alleged female victim was actually a "crazy fan who attacked" her.
Delp declined to comment on the matter.
Earlier this year, Evans was arrested for assault when video footage of the 19-year-old attacking another young woman appeared online.
