Mr Nimalaraja, who worked at the Leicester Stores, died in hospital after being punched to the ground during an altercation with youths near the shop at the junction of Gypsy Lane and Northfield Road.
The boy had claimed he was acting in self-defence after accusing Mr Nimalaraja of picking up a piece of wood to attack him during an altercation with youths at the junction of Gypsy Lane and Northfield Road.
Bailiffs were due to evict the 10 Gypsy families living at Shurlock Road in Waltham St Lawrence earlier but action has been suspended by the High Court.
There is currently only one legal gypsy and traveller site in Swansea, at Pantyblawd Road, which the council said had been "fully subscribed for some time".
