The police on Sunday said they had arrested 51 people over scam cases involving HK$99 million during a week-long crackdown on con artists.
The suspects have been released on bail and ordered to report to police next month.
The people arrested are suspected of money laundering and obtaining property by deception in 39 different scam cases, resulting in financial losses for 119 people.
Officers said that they launched the operation last Sunday in response to a growing number of scam complaints. They also warned people to stay vigilant and secure their personal data.
