Police discovered the group congregating around a small sound system shortly before 9pm on Wednesday night, just 24 hours after the area saw widespread disorder on Tuesday including a rape, fights and illegal fires.
Officers also said that two men had been arrested over a separate incident in the park yesterday, with one being charged with drug and weapon offences and bailed and the other being released on police bail.
Superintendent Simon Verrall said: “There were many people in Endcliffe Park yesterday enjoying the sunshine and in the main this was all in good spirits however on a couple of occasions, officers had to engage with small groups to remind them of the requirements of the COVID restrictions.
“At around 8.45pm a group gathered around a small sound system playing loud music. This was a breach of COVID restrictions so advice was offered and over a short period the group was dispersed.
“Officers will maintain a high visibility presence across the week to provide advice where needed and offer reassurance to anyone who may need it given the events of recent days.”
Following a separate incident also in Endcliffe Park, 25-year-old Devon Gregory from Heeley was charged with possession of a pointed or bladed instrument and possession of a class B drug.
He is bailed and due to appear in court on 13 August 2021. A 32-year-old man was also arrested and released on police bail.
