A trash collection worker has died after he fell from the truck or collapsed while riding on the back.

WMTW-TV reports that the incident happened late this morning in Lewiston, near the intersection of St Gerome and Gina Streets. The driver of the truck called 911 to say that a worker had fallen off the back of the truck and was lying in the street.

Police aren't sure, at this point, whether the 31-year-old fell off the truck and hit his head on the pavement or whether he collapsed due to a medical issue. The driver told police that the workers had stopped to pick up some trash and he drove forward a short distance. When he looked back, he saw the man in the road.

The man, who is an employee of Pine Tree Waste, died early this afternoon. Police have not yet released his identity, pending notification of his family.
