A police officer who was duty-bound to report suspected loan sharks borrowed from them instead.
Idris Makrob, 37, was working for the Criminal Investigation Department when he frequented Base Music Jourdan Sing-A-Long in 2006.
He bought a 2.5 per cent stake in the establishment at Changi Village, paying just $500.
The pub had employees who did not have valid work permits, and believed he could provide 'assistance', reported The Straits Times.
Idris discovered that three shareholders were running a loan-shark business, and borrowed money from them.
These three shareholders have since been arrested, while Idris was sacked from the police force.
Idris pleaded guilty to two charges of failing to report illegal activity and going into business without getting permission from the Commissioner of Police. Two similar charges were taken into consideration.
He was jailed 10 weeks - the two 10-week jail sentences for the two charges will run concurrently.
The former officer said he regretted what he had done, adding that the four years that he was under investigation were 'traumatic' and 'excruciating'.
Along the way, he also had to cope with the death of his infant son and a divorce.
He could have been jailed for up to six months and fined up to $1,000 on each charge.
