Brentwood concrete crash driver 'could have died'
A driver "could have been killed" after he struck concrete thrown on to an Essex A-road, police said.
The piece of rubble, about the size of a fist, was thrown from a bridge and landed on the Southend-bound carriageway of the A127 at Brentwood on Saturday morning.
Essex Police said the concrete hit the front end of the Ford Focus, causing £2,000-worth of damage.
The force has appealed for witnesses to come forward.
It is believed the concrete was thrown from the bridge at the A128 Halfway House junction at about 01:00 BST.
The possibility that it came loose from the bridge itself has been ruled out.
Det Insp Mark Barber said: "Fortunately only the victim's car was damaged, but he could have been killed or seriously injured if he'd had to swerve off the road or if it had crashed through the windscreen and hit him.
"If anybody saw anything suspicious in the area, or who knows of anybody who may have been involved, please contact officers at Loughton as soon as possible."
