He was sentenced on 26 November to eight months and 17 weeks imprisonment as well as a fine of $5,500.

Previously spent 18 years in jail
Clarence had spent a total of 18 years in jail for different offenses over the years.
He received an early release from jail this year on 2 January and was supposed to stay out of trouble.
With his latest offenses, he will have to spend another 22 days in jail for breaking the rules of his remission order.
Clarence was drinking beer on 7 March this year with 3 other friends at Teck Whye Lane and was making a lot of noise near a supermarket.
The police went down at around 9pm following a complaint about the noise and saw Clarence’s mask not being worn properly.
One of the officers told him to put it on properly and he (Clarence) got agitated and challenged the officer to a fight.
Clarence was then detained and the officers found 11 grams of fragmented vegetable matter inside his bag during a search, which turned out to be a synthetic drug.
Paraphernalia to consume the drug was also found.
When I come out, I will find you
The man was then arrested and taken to Woodlands police division, and Clarence then spat at one of the police officers who was sitting beside him inside the police car.
He also showed him thrice with his knee before turning to the officers and saying: “When I come out, I will find you.”
