John Lever, who's caught more than 100 crocodiles in the past, is heading home after the 1.2 metre reptile outwitted his efforts to catch it.
Two Chinese croc hunters have now taken on the challenge to catch the creature.
The croc was first spotted a month ago. Hong Kong has no native crocs so it's a mystery why this one turned up.
It seems the croc's being a bit shy at the moment.
It hasn't been spotted for several days, but Mr Laver reckons it will show up again in the next three or four weeks.
He told Hong Kong residents to keep an eye out for the croc and offered them some advice on croc hunting.
"If you get within grabbing distance, just grab it," he said.
"If you worry about being bitten, you'll never catch a crocodile."
