A14: Update - Man Dies After Crash With Horses
A man's died after four cars collided with loose horses on the A14 in Suffolk.
The 23-year-old from Cambridgeshire was taken to Ipswich Hospital after the crash at Sproughton. He died on Christmas Day.
Police were called to the scene of the collision at 10.20pm on Christmas Eve after a report that 5 or 6 horses were loose on the A14 and four vehicles had been involved in a collision with the horses.
A section of the A14 westbound carriageway between Copdock and Sproughton was closed in order to recover the vehicles and horses, three of which died as a result of the collision.
The A14 has now re-opened.
A 26-year-old Ipswich man arrested on suspicion of causing danger to road users, has been bailed pending further enquiries and will return to the Martlesham Police Investigation Centre on 28 February 2013.
Witnesses to this incident are asked to call PC Ali Cotton at the Serious Collision Investigation Team at Suffolk Police on 101.
