Police in Canada are investigating two suicides which may be linked to the hacking of cheating website AshleyMadison-dot-com.
The details of 37 million users were dumped online by a group of hackers last week.
Ashley Madison's parent company is offering a reward for help catching those responsible.
Superintendent Bryce Evans from Toronto Police said the hack "has, and will continue to, have a long term social and economic impact, and they have already sparked spin-offs of crimes and further victimisation."
A group calling themselves Impact Team have taken credit for the hack.
Avid Life, the parent company of AshleyMadison, has offered a $500,000 reward for information on the hackers.
"Today I can confirm that Avid Life Media is offering a $500,000 (£240,000) reward to anyone providing information that leads to the identification, arrest and prosecution of the person or persons responsible for the leak of the Ashley Madison database," Mr Evans said.
