More than 30 young people were moved on by police after gathering and causing trouble at a Llanelli McDonald's.
Dyfed-Powys Police received reports on Sunday evening that the youths were behaving anti-socially at the fast food chain branch at Trostre retail park, and in the car park area.
A Section 34 dispersal order was put in place giving police the power to move anyone believed to be causing a nuisance, harassment or distress out of the area.
