At least 30 suicides from 2020 to 2025 were identified in connection with allegations of cyberbullying, online humiliation, blackmail, or the circulation of personal images and videos.
Most of the people described in those cases were between 14 and 25 years old.
The cases include allegations of hacked social-media accounts, fabricated sexual content, coercive demands for money and abusive online campaigns.
Families in several cases alleged that online harassment or blackmail contributed to severe distress before the deaths.
Dr Niaz Mohammad Khan of the National Institute of Mental Health said many people who die by suicide experience depression over a prolonged period.
He said cyberbullying has become a suicide-risk factor, while family pressure, social stigma and mental-health conditions can compound a victim's distress.
CID data cited in the evidence place cyberbullying and harassment at 50.27% of cybercrime victimisation.
Women and girls account for about 80% of people targeted by cyberbullying and blackmail, the cited CID figures indicate.
Additional Superintendent of Police Abu Taleb said many victims of cyber harassment do not seek legal help, allowing many accused people to remain beyond the reach of law enforcement.
Rights organisation Ain o Salish Kendra recorded between 500 and 700 women each year in recent years as victims of killing or suicide, with domestic violence, dowry, sexual harassment, relationship strain and social abuse among the cited factors.
The available evidence does not establish cyber harassment as the sole cause of any individual death.
