• Rotorua crime on the rise (+video)
"After that day when I was threatened my perception changed and I realised I had to be more careful.
"But it wasn't just my perception that changed, I changed too - now I check out every person's face, I started going to the gym and when at the counter I stand in a way that shows I'm not scared."
Mr Singh said he had 15 cameras in his liquor store, did training on how to react in threatening situations and ensured there were two people rostered on at all times.
"I keep thinking how lucky I am that my friend was in the store at the time I was threatened because if I had been alone I think it would have been a different story.
"I think had the offenders not been caught by the police I would feel more like a victim, I'd still be scared."
He said while people had stolen from his store since, he had thankfully not been threatened again.
"A lot of the time people try to walk out with stuff, like a grab-and-run move, I am very thankful I have only been confronted that one time."
Mr Singh said he thought the crime figures were not a reflection of the good work done by Rotorua's police.
"The police do a wonderful job, I don't think the rise in crime is because they are not working hard, I think it has more to do with people being more bold and attempting to commit crimes more often."
