Here is the text of the statement:

"Our hearts go out to the families of those involved in a terrible accident this morning that involved one of our concrete mixer vehicles.

"According to the information available to us, a truck carrying a number of workers collided with one of our vehicles. The police are involved in an extensive investigation and our driver has provided his own account of the circumstances that led the truck with the workers to veer into the oncoming lane and collide with our vehicle, apparently while trying to avoid a third vehicle."
