Thames Valley Police is appealing for witnesses after burglars broke into a city pub on Saturday.
Between 5.15pm and 6.15pm, offenders forced into The Malsters Arms on Aylesbury Street while it was closed.
They climbed a flight of outside steps to the roof of the building, smashing a window to gain entry into the first floor flat. They plugged the bath in and left the tap running, overflowing the flat, before going into the pub and stealing alcohol worth £100.
In the process, the burglars also stole the landlord’s car which was later found burnt out near to the Lakes Estates.
The fire brigade were called later to stop the water flowing through the ceiling.
Detective Constable Sam Reynolds, from Milton Keynes police station, said: “This was a Saturday evening and there was likely to be people in the area.
“I would like to hear from anyone who noticed suspicious activity around the pub or if they know anyone who has acquired a quantity of alcohol as this information is important in our investigations.”
