Wiltshire Police are appealing for information after a memorial bench in Amesbury was vandalised.
The bench at the Glenn Collier Skate Park in Southmill Hill was damaged sometime between March 4 and 5.
Flowers placed nearby to mark an anniversary were also thrown on the ground.
PC Thomas Morgan said: “This bench was put in place at the skate park in memory of BMX rider Glenn Collier who died in 2019, and understandably this incident will cause upset to his family and friends and those who use the park regularly.
“Our enquiries to identify those responsible are ongoing and we would urge anyone who witnessed the incident or anyone with further information to contact police.”
