Police Scotland is appealing for information after a defibrillator located at Market Square in Oldmeldrum was vandalised.
Officers were made aware that the perspective cover which protects the equipment had been smashed and removed between 5pm on Friday 14 and about 10am on Monday 17 July.
PC Scott Walmsley, who is leading enquiries, said: "This has been a completely senseless act of vandalism. The cost may be low to fix, however it is not the point - this is a piece of equipment generously donated from funds by the local community which is there to save lives.
"It is beyond belief that someone could do this and extensive enquiries are ongoing to trace the person - or people - responsible. I would urge anyone with information that could assist to contact Police on 101 as soon as possible or Crimestoppers on 0800 555111 if you would prefer to remain anonymous."
Meanwhile Aberdeenshire East MSP Gillian Martin said she was “shocked” by the incident.
She said: “I am really shocked to hear of this incident. Defibrillators can provide life-saving treatment for those in need.
“This is a completely senseless act. The funding for this equipment was provided by the local community.
“It is there to save lives and I would urge anyone who thinks they may know something to come forward.
“I welcome the hard work of local officers to trace the person or people responsible.”
