One of the Bishan-Ang Mo Kio Park otters appears to be injured and limping after it was deliberately baited with a fishing line hook.

The incident happened on Oct. 20 at around 6.30pm at the canal along Toa Payoh Lorong 8.

The illegal fishing act was caught on video and posted on YouTube by Fast Snail, a chronicler of Singapore's otters.

A man in blue was clearly seen using his line to bait the pup, which was later seen and heard in the video to be squeaking in distress as it got caught by the fishing line hook.

The pup later managed to break free and swam away with its family as it appeared that the line broke.

The angler was seen smiling when he successfully baited the pup:

In another video posted by Fast Snail on the same day, the otter pup that was baited can seen with a line and float extending from its right hind leg, which appears immobilised, as it limped along on its other three legs.

The angler in blue has since been visually identified by Fast Snail:

Earlier that day on Oct. 20, the family of five otters had paid St Andrew's Junior College a visit.

In a video posted by the school, the five otters appeared fully healthy.
