A Dubuque teen now faces adult-level charges connected to two serious assaults in May -- one of which led to a girl being taken to an Iowa City hospital for treatment.

Rickey A. Carter, 17, of 824 Lincoln Ave., was charged this week in Iowa District Court for Dubuque County with assault causing serious injury-without intent to cause serious injury and participating in a riot, both felonies. He also faces misdemeanor charges of fifth-degree theft and interference with official acts.

Court documents obtained today state that the case started in juvenile court.

According to documents, Dubuque police investigated a large disturbance that occurred May 3 on West 15th Street near Iowa Street. Traffic cameras showed Carter and six other "male subjects" get out of vehicles in that area and pull a 17-year-old boy out of 37 W. 15th St. and into the street.

Documents said Carter and his six companions assaulted the boy by "punching him, kicking him, throwing a bicycle at him and throwing a scooter at him, all while (the boy) is on the ground in the fetal position."

Police said the investigation into that assault is ongoing and criminal charges are expected to be brought against others involved. 

Carter also is accused of assaulting a 16-year-old girl on May 14. The girl said she was riding in a vehicle with Carter near Flora Park when he stopped and hit her in the head three times. Her injuries included a "depressed skull fracture and subdural hematoma," which required treatment at University of Iowa Hospitals and Clinics in Iowa City. 

Documents state traffic camera footage also captured that incident.

The names of the two assault victims have not been released. 

Documents also state Carter is accused of shoplifting items from a Dubuque gas station on April 11 and fled from a traffic stop on June 11.
