Police officers were stuck in the mud for 45 minutes on Wednesday evening after their vehicle ran into trouble in the Springfield Avenue area of Belfast.
As officers approached to move on dozens of young people playing music, their Land Rover mounted the curb and drove onto saturated grass.
It became stuck in the in mud, leaving the officers vulnerable to attack in an area where dissident republicans operate.
As the stricken vehicle awaited assistance at Millennium Way between Cluin Mor Avenue and Forfar Street, it was pelted with bottles and rocks.
The vehicle was eventually towed out of the mud by another PSNI Land Rover.
Members of the Beechfield Residents Collective last night expressed outrage at the young people “being a nuisance in general”.
Some appealed to the parents of children “to make sure you know where they are and not torturing the good people of our community”.
