Vandals caused a chemical spill after upending portable toilets in a Lockerbie park.
Organisers of Lockerbie Riding of the Marches had to put up a warning notice on their Facebook page after the incident, which is believed to have happened on Saturday evening just before the massed bands and beat the retreat.
Eye witnesses saw a group of eight “young lads” running out of the Dumfries Road gate of McJerrow Park, which hosted Saturday’s gala day turn-up.
