A 19-year-old man faces charges of child pornography and revenge porn after allegedly threatening to publish intimate material of his 17-year-old former girlfriend, police said.
The girl's mother filed a complaint with the Cybercrime Division, reporting that the man began threatening her daughter after she ended their relationship in August.
The relationship had lasted less than three months.
The mother told police the 19-year-old had exerted psychological pressure on her daughter and displayed "excessive jealousy" during their time together.
After the breakup, the suspect allegedly sent repeated messages and made phone calls, threatening to share private videos with the girl's family and friends.
Police said he also threatened to kill himself or harm others.
The suspect was arrested at his home, where officers confiscated a mobile phone believed to contain the incriminating material.
He is expected to be brought before a prosecutor.
