High speed largely is to blame for a head-on crash that injured several people, including children, on Grand Rapids' North Side.

A car traveling north on Coit Avenue near Hubbard Street NE crossed the roadway's center line and crashed into a car heading south, said Grand Rapids Police Sgt. David Siver at the scene.

The crash happened around 7:10 p.m. Sunday, April 2.

Seven people are involved in the crash, but it's not yet clear who was injured and who escaped relatively unscathed. At least three kids are among those in the crash, Siver said.

It's believed the driver was traveling at a "very significant" speed, he added. An investigation is underway to determine whether drugs or alcohol were involved.

A neighbor in the area earlier told WZZM 13 he saw at least two people on the ground needing medical treatment, and another person pinned inside their vehicle. One of the vehicles involved in the crash caught fire, but it was quickly put out.
