He was on the tail end of his extended national service when he heard there was a fight in Arab Street.
As full-time national service inspector (NSI) Muhammad Azhar and his partner were patrolling the area that night in March, they went to investigate.
When he got there, he saw a man behaving suspiciously. He and his partner approached the man, who turned hostile when asked for his particulars.
"He started pushing me and my partner," said the 20-year-old.
"He taunted us, saying, 'What are you going to do? I can push you but you cannot push me.'
"We followed protocol and asked him to step back, but he refused to listen."
NSI Azhar and his partner then grabbed the man's arms and handcuffed him.
"We searched him and found a broken glass bottle hidden in his back pocket," he said.
"Thankfully, he didn't have the chance to take it out and use it."
The man, who was intoxicated, was arrested for possession of a dangerous weapon.
The incident was just one of many NSI Azhar had to handle after voluntarily extending his service with the Singapore Police Force (SPF) for just over three months after his national service, which ended in December last year.
During his service, he also volunteered to do patrol in Little India following the riot in December 2013.
"I had an advantage in terms of the Tamil language, which really helped," he said.
