SINGAPORE - A man who threw a rock glass at his friend and caused a permanent scar on his face was jailed for four months on Friday (May 20).

Dexter Lee Rui Sheng, 27, then a business development manager, pleaded guilty to causing grievous hurt to Mr Benedict Poh Feng Qi by doing a rash act to endanger the personal safety of others at Grand Oasis pub at The Verge along Serangoon Road on Feb 5, 2013.

The court heard that at about 2.30am that day, Lee, Mr Poh, 29, and Mr Darren Tan Yong How, 26, went to the Grand Oasis pub with some friends for drinks.

Lee and Mr Poh were playing drinking games while seated at a rectangular-shaped glass-top table when Lee asked him to drink more alcoholic drinks.

Mr Poh declined but Lee kept asking him to drink some more. This led to an argument.

Mr Poh was standing about 45 degrees across the table from Lee when the latter took a rock glass and threw it at him,

The glass smashed into the left side of Mr Poh's face, causing a cut.

When the group were unable to stop the bleeding, they took him to Tan Tock Seng Hospital.

Mr Poh suffered a 5cm cut and two smaller superficial cuts on the left side of his face.

According to the doctor, the victim's injury would result in a permanent scar on his face.

Mr Poh, then a salesman, filed a magistrate's complaint against Lee for an alleged case of causing hurt on Feb 19 that year. The magistrate directed that the police conduct investigations into the matter.

Lee, who was represented by a lawyer, said he was sorry that he injured his friend, and that he had no intention of doing it.

His lawyer said the father of two had accompanied the victim to the hospital and stayed unitl Mr Poh's parents arrived.

The maximum penalty for causing grievous hurt by doing a rash act is four years' jail and a $10,000 fine.
