Thames Valley Police have released a CCTV image of a man who could have vital information about an ABH incident that took place in Bletchley on Wednesday night.
The victim, a 50-year-old man, left the Premier shop in Water Eaton Road at about 9.55pm and walked to his bicycle which was left outside.

The offender assaulted the victim again before leaving the scene.
The victim sustained head injuries as a result of the incident, but did not require hospital treatment.
