A bartender tracked down his ex-girlfriend through pictures she posted on photo-sharing site Instagram and then slashed her male companion, severing one of his fingers completely.
The victim turned out to be her cousin. On Monday, Muhammad Nurafiyan Mohamed Sani (photo), 20, was sentenced to three years in jail and six strokes of the cane.
He had pleaded guilty last week to causing grievous hurt to Muhammad Mifdah Rosli, 21.
The court heard that Ms Nurul Atikah Abdulla, 20, was at the Azzura Club in Sentosa on the evening of June 8. There, she took a picture of herself and uploaded it onto Instagram.
Muhammad Nurafiyan noticed that the picture was also tagged under Mr Muhammad Mifdah's name and became annoyed. He then identified the other man from one of her pictures.
Ms Nurul Atikah had planned to go to a chalet in Pasir Ris later and he called her and demanded that she give him the address. She refused and hung up on him.
In the early hours of June 9, Muhammad Nurafiyan found out that his friend Ahmad Taqlyyudin Rosli, 22, was also at the same chalet through pictures on Instagram, and he got the address from his friend.
Muhammad Nurafiyan and another friend Muhammad Faris Kamal took a taxi to the chalet.
Both were armed with knives.
The duo had asked Mr Ahmad Taqlyyudin to tell Mr Muhammad Mifdah that someone was coming over to give him something.
At the meeting in a nearby hall, they attacked Mr Muhammad Mifdah without warning.
The victim tried to explain that he was merely Ms Nurul Atikah's cousin, but to no avail.
His face and shoulder were slashed and the index finger of his right hand was completely cut off.
The attackers fled and Muhammad Nurafiyan threw the 40cm-long knife he had used into the Kallang River.
He then went into hiding.
Doctors tried to reattach Mr Muhammad Mifdah's severed finger but it later developed gangrene and had to be amputated.
On June 21, Muhammad Nurafiyan was stopped by police at Bugis+ shopping mall. He managed to escape but officers found 0.61g of methamphetamine or Ice in the sling bag he left behind.
On Monday, he was also sentenced to one year in jail for drug possession, which means he will serve a total of four years in prison. He could have been jailed for up to 15 years and caned up to 24 times for causing grievous hurt, and up to 10 years and fined up to $20,000 for possessing drugs.
Muhammad Faris, 23, who works as a mover, has been charged but has not been dealt with.
