A man has been arrested on suspicion of drug driving after a motorcyclist was killed in a crash with a lorry on the A14 outside of Ipswich.

The incident happened on the eastbound carriageway between Sproughton and the Copdock Interchange shortly after 6am on Wednesday.

Police, fire crews and the ambulance service were called to the incident, but the rider of the motorcycle, a 61-year-old man, was pronounced dead at the scene.

The driver of the lorry, a man in his 30s, was subsequently arrested on suspicion of causing death by dangerous driving and driving with excess drugs.

He was taken to Martlesham police investigation centre for questioning, where he remains.
