Later this morning, at about 2.25am, a 26-year-old man was arrested near Washbrook in connection with the incident.

He allegedly failed a roadside breath test and was taken into police custody for questioning, but has since been released under investigation.

According to the police spokeswoman, neither the young child or driver sustained any injuries.

The A12 was closed in both directions for about four hours to recover the van and clear debris from the carriageway.
