One of the witnesses also took a photo of Wilkinson-Alcock and Lamb as they left the scene.
Officers visited Lamb’s home where they arrested him on suspicion of assault occasioning grievous bodily harm (GBH) to which Lamb claimed it wasn’t him and it was “the guy upstairs”.
Police went upstairs and found Wilkinson-Alcock wearing a dark blue rain jacket and with his dog, which matched witness descriptions. He was arrested on suspicion of the same offence.
A search of the house uncovered a grey hooded top with yellow writing on, which was covered in blood stains. This jumper matched the clothing seen in the photo taken by one of the witnesses.
