Do you recognise the shorter man in these pictures?
Officers are keen to speak to him following two suspected assaults in Cliff Street, Bridlington, in the early hours of Sunday, December 18, which left one victim with a broken jaw and the other unconscious.
The first happened at around 4.14am, when the 30-year-old victim was walking towards Promenade and was passed by two men, one of which is said to have assaulted him.
The victim then followed the men to Tasties takeaway in Cliff Street, where it is said his attacker then assaulted a 26-year-old man, who fell to the floor and lost consciousness for a short time.
The 30-year-old later underwent surgery to his jaw at York Hospital. The 26-year-old man was treated at the scene by paramedics.
Anyone who witnessed either assault, or who is able to identify the man or anyone who was with him at the time, is asked to call 101 quoting crime reference numbers 2237416 and 2237094 respectively.
