Police are appealing for witnesses after "anti-COVID-19 graffiti" was sprayed on two vaccination centres in Bournemouth.
The vandalism happened at Bournemouth International Centre and Westbourne Medical Centre.
Dorset Police said they were sprayed with "anti-COVID-19 graffiti relating to the current vaccination scheme that is underway".
Signs, paving stones, concrete areas and a building were vandalised at around 2am on Sunday 16 May at Bournemouth International Centre.
A call on Monday morning revealed similar graffiti at the medical centre, with the damage believed to have occurred around the same time as the first incident.
CCTV images of the suspect have been released.
Police Sergeant Chris Vaughan said: "This mindless damage has caused great inconvenience to both centres at a time when the vaccination programme has had to step up a gear in response to the COVID-19 pandemic.
"A full investigation is underway into both incidents.
"We have obtained CCTV images of the suspect from the BIC incident and, although the quality is not very good, I would urge anyone who recognises this man to please contact Dorset Police."
