The victim, a man aged his 30s, was treated at the scene by paramedics but he was sadly pronounced deceased a short time later.
A scene remains in place while an investigation into the circumstances continues.

He was subsequently further arrested on suspicion of murder and was taken to Martlesham Police Investigation Centre for questioning.
