Officers believe he may have information to help their investigation.
Officers hope to identify the man photographed, who was walking down Jacks Lane at around noon on Friday 1st March.
They are keen to stress he is a witness and is not in any way connected with the crime.
The witness was spoken to by another man who was walking his dog and who appeared to be in an agitated state. Police would like to know what the conversation was about.
The man in the agitated state is suspected to have later been involved in an incident in which damage was caused to a property and vehicles in Jacks Lane.
A 46-year-old man from the Torquay area has been arrested on suspicion of criminal damage and affray and has been released under police investigation.
Anyone with information about the incident, or who can help identify the witness pictured, is urged to call police on 101, or email firstname.lastname@example.org, quoting crime reference number CR/018799/19.
