40-year-old South Korean Kim Sun Ho, pleaded guilty to voluntarily causing hurt to a public servant and was sentenced to 10 weeks imprisonment on Friday.
He had punched a policeman in the face after they showed up to look into complaints of excessive noise at a party that he was in.
Kim had been drinking before the incident on 20 February, at a gathering in Ocean Drive, Sentosa Cove.
The Sentosa Cove security received a noise complaint and a security officer then went to look into it and noticed that Kim was drunk, rowdy and uncooperative.
The security officer then called the police, and Special Constabulary Sergeant (1) Harith Syahmi Safarudin and his colleagues then arrived at the scene of the incident at about 3.15am.
Kim emerged from a bedroom to look for one of his female friends when the police arrived, and he then stumbled into the patio where his friends were and almost fell into the swimming pool because he was drunk.
The police officer (who was punched by Kim) then pulled Kim’s arm to stop him from falling into the pool, and Kim then told him to “shut up”, before throwing a punch at the officer’s left cheek.
He then tried to throw another punch at the victim’s face but was restrained by 2 other officers, before being arrested.
He later admitted to drinking multiple glasses of champagne and whiskey before the incident.
The victim was given 2 days of medical leave after suffering a bruise on his left cheek.
