An Indian-origin Singaporean serial prank caller was sentenced to three years of imprisonment on Thursday for repeatedly making nuisance calls to the police, despite being jailed for the same offence previously.
Gurcharan Singh, a 61-year-old cleaner, usually made the "999" emergency calls after drinking alcohol, the court heard.
The latest incidents occurred over two days in June, with Singh making two calls on the first day and 15 on the second.
On June 10, Singh called the police using a public phone at a void deck of an apartment block in Chai Chee housing estate.
In one of his calls, he told the operator: "You are stupid." He also said: "I put one dynamite to the immigration house."
