A defibrillator at a rugby club was vandalised last week.
Police are now appealing for witnesses to the incident at Haverhill Rugby Club to contact them.
It is thought the incident happened between 8pm on December 2 and 9am the following day.
Suspects used white paint to damage a defibrillator cabinet and a wall at the front of the sports club.
A name was spelt out in the paint. The cabinet has now been cleaned and the defibrillator remains in use.
Witnesses or anyone who may have any information should contact Suffolk police on 101.
