A dog walker threw a cup at another dog walker in a late-night dispute over how they reacted to their animals barking at each other in Ipswich.

The victim of the common assault in Sheldrake Drive was “shocked” by how the other dog walker reacted to restraining the Staffordshire Terrier he had taken out for a walk.

Both the victim, a man in his 40s, and the suspect, described as white and in his 20s, had each taken out a dog for a walk at around 8.45pm on Sunday.

Police are investigating the common assault and are asking for the suspect and witnesses to come forward.

A Suffolk Constabulary spokesman said: “(They) were both out walking dogs when the animals began barking at each other.

“The victim was shocked by how the other dog walker reacted to restrain his dog – a brown Staffordshire terrier type – and challenged him about his behaviour.

“A cup was then thrown at the victim, striking him on the arm.”
