A wild otter from the famous Bishan-Ang Mo Kio Park pack known as the Bishan 10 has been hurt by a fishing hook.
The otter is likely to be a victim of illegal fishing.
Photos by Facebook user Fast Snail showed otters trying to remove a fishing line which had caught the injured otter close to its right eye.
The Wildlife rescue group, Animal Concerns Research and Education Society (Acres) said it was made aware of the incident on Saturday evening. They have not been but able to locate the otters.
A spokesman said: “We appeal to members of the public to contact us if they see the otters so we can offer the necessary help. We would also like to remind the public not to fish at illegal sites.”
Fishing is not allowed in waterways and anyone caught doing so can be fined up to $3,000.
