Detectives have released CCTV images of a man they want to speak to in connection with three assaults in Northampton town centre this summer.
The attacks took place between 4am and 4.30am in Horsemarket, near to the Base and Fever nightclubs, on Monday, June 4.
Officers have today released these CCTV images in a bid to get witnesses to come forward.
Three men, aged 23, 29 and 32, all received facial injuries in the attacks.
