Four people have been arrested on suspicion of criminal damage, possession of a Class A drug and disorderly conduct - for an incident where a woman had to be taken to hospital.
In the early hours of Tuesday, police were called to assist a vulnerable woman in Waitrose car park, Buckingham.
A large group of youths were in the same car park, and were verbally and physically abusive to the attending officer as he attempted to carry out his duties.
The woman was taken to Milton Keynes hospital; when the officer returned to his vehicle in London Road, Buckingham, the wing mirrors and rear lights had been smashed and the tyres slashed. A police dog was inside the vehicle, but was unharmed.
Insp James Davies, from the local neighbourhood police team, said: “This sort of anti-social behaviour will not be tolerated in Aylesbury Vale. This officer was dealing with a vulnerable person who needed help and I find it incredible that anyone would try to divert him from doing this. The damage caused was substantial; we will be requesting compensation from those who are responsible for the attack.”
The four were arrested on Tuesday, and taken to Aylesbury police station.
A 27-year-old man from Gawcot has been bailed to 29 December, a 26-year-old man from Buckingham has been bailed to 29 January, a 16-year-old boy from Buckingham has been bailed to 13 January, and a 15-year-old boy from Stowe has been bailed until 29 December.
