British national Benjamin Glynn, 40, is accused of failing to wear a mask between about 10am and 10.30am within and outside the State Courts on Jul 2.
Glynn appeared in court that day to face multiple charges - one count each of failing to wear a mask without reasonable excuse, public nuisance and using threatening words towards a public servant.
He had his bail of S$5,000 revoked on Monday and was remanded in custody. As part of the bail conditions set on Jul 2, he was not to commit another offence while out on bail.
He showed up without wearing a mask and put it on only after court officers spoke to him. He was reminded twice by the judge to wear his mask properly.
Glynn is accused of failing to wear a mask outside his home while he was travelling from Raffles Place MRT station past 11pm on May 7. He also allegedly committed an act of public nuisance by declaring "I will never wear a mask" while on the train.
Two days later, he allegedly told two police officers at the lift lobby of Allsworth Park, a condominium in Holland Road: "I'm gonna f***ing drop you."
In the video circulating on social media, Glynn was seen in exercise wear on an MRT train. He did not have a mask on and was speaking to other commuters about masks.
Glynn is scheduled to return to court on Jul 23.
