Waterloo police have arrested a man they say was involved in a hit-and-run that injured a child last week.
Police arrested 31-year-old Justin Varney at his home Saturday night. Police think Varney hit an 8-year-old boy with his car last Monday, and then drove off.
The 8-year-old victim sustained minor injuries in the incident.
Varney is in the Black Hawk County Jail facing charges related to the hit-and-run as well as a probation violation.
