Police are appealing for any information after a mysterious 'help' sign was spotted at a remote West Coast lake.
The large message written in the sand was spotted by a helicopter flying over Lake Ahaura, east of Greymouth, in an area surrounded by thick bush.
"We are asking to hear from anyone who knows of parties having gone into that area recently," a police spokesperson said in a statement on Friday.
"We would also like to hear from anyone who may have written the message and who may now be safe and well."
If you can help, please call 105 and quote event number P055875858.
