POLICE have released a picture of a man they want to speak to about a dog attack.

A long haired Alsatian bit a man on the hand in St John's Road, Colchester, last Saturday, September 16, at roughly 3.10pm.

The victim was bitten after his Cockapoo was chased by two long haired Alsatians.

The dogs then attacked a Cocker Spaniel, causing a puncture wound to its side.

The owner of the Alsatians left with his dogs and refused to give his details.

Anyone with information is asked to contact Colchester police station on 101 or Crimestoppers anonymously on 0800 555 111.
