CEDAR RAPIDS, Iowa (AP) -- Cedar Rapids police say a 31-year-old father has reported that two people tried to abduct his son.

The department said Wednesday that the father told officers that he was riding his motorcycle on a street around 5:30 p.m. Tuesday, trailing his 5-year-old son who was riding a bicycle on a sidewalk.

The father says a van stopped next to his son. He says a man and woman got out, grabbed the boy and his bike and then began pushing them toward the van.

Police say the father reported the incident about three hours later.
