All the suspects made the plea when the charges were read separately before Magistrate Rosnee Mohd Radzuan.
They were accused of committing the offence at a field of College General around 5.30pm on March 31.
They were charged under Regulation 3(2) Prevention and Control of Infectious Diseases (Measures within Infected Local Areas) Regulations 2020.
The accused, aged between 25 and 48, were ordered to carry out social service work under the guidance and supervision of a parole officer, in default of three months’ jail.
Rosnee said the compulsory order takes effect on Thursday (April 2), and the accused must carry out their social service work for three hours on working days for a duration of three months.
On Tuesday (March 31), the suspects were arrested by police after they were found playing football at a field located in the compound of the college.
The arrests resulted after police were tipped off by a resident of a nearby apartment who had taken a picture of the men playing football.
