A Newcastle University professor will be sentenced for scratching polite graffiti on luxury cars and causing thousands of pounds worth of damage.
Stephen Graham, who had been drinking, admitted attacking the cars - including a Mercedes and an Audi - when they were parked in Jesmond last year.
He used a screwdriver to scratch "very silly", "really wrong" and "arbitrary" onto cars, among other messages.
The 47-year-old, who works as an expert in cities and society, admitted four counts and asked for 23 similar offences to be taken into consideration when he appeared in court in January.
It was said he had no recollection of what happened on the night in August 2012 in Northumberland Gardens, a few streets from his home.
At a previous hearing he blamed a bad reaction to alcohol, antibiotics and prescription drugs for his behaviour.
