Two stolen bicycles were recovered because they sported police-issued security labels.
Police said on Saturday that arrests were also made in those two separate cases.
While conducting checks on a group of youths, police found one such label on a bicycle they had in their possession. Further checks revealed that there had been a report of a stolen bicycle with the same label number. Three youths were arrested and the bicycle has been recovered.
In the second case, police found another security label on a bicycle secured to a metal railing along a walkway, and confirmed that its owner had lodged a report earlier. The suspect was arrested after an ambush was laid.
Police advised the public to keep their bicycles at home and lock their bicycles when they are left unattended. Owners can also label their bicycles with free security labels available at any neighbourhood police centre.
The rectangular label, which allows a bicycle to be tracked if stolen, was released in collaboration with the National Crime Prevention Council two years ago in 2011.
