A Michigan man who stalked an 18-year-old Radnor Township resident famous on YouTube and Instagram messaged the teenager's mother that he was going to abduct her son, then showed up at the family's home at least three times, according to police.

Michael Leib, 30, of Plymouth, Mich., was arrested Tuesday outside the Radnor home and charged with stalking, harassment, and terroristic threats. His arrest was announced Friday by township police. The alleged victim's name is being withheld by the Inquirer and Daily News.

According to the criminal complaint, Leib twice appeared at the Delaware County home on Oct. 25. The next day, he sent direct messages on Instagram to the teenager and his mother that read, in part, "I want to have sex with your son" and "I am going to take your son," police said.

The victim, who has 140,000 followers on Instagram and 18,000 followers on YouTube, said he did not know Leib, who, online, went by the name Michael Dombrowski, according to police.

Leib continued to send messages threatening to take the teenager from his home and have sex with him, the complaint said.

The family called police Tuesday when they spotted a suspicious person at their front door and in the backyard. He was gone by the time authorities arrived.

A detective took the teenager to the police station that day and asked him to send a message to Leib in an effort to lure him back to the house, according to the affidavit. The victim did so and a few minutes later, Leib was spotted and arrested outside the residence, authorities said.

In interviews with police, Leib admitted to driving nine hours from Michigan to Radnor on "numerous occasions" because he was attracted to the victim and wanted to have sex with him, according to the criminal complaint.

Radnor Police Lt. Shawn Dietrich said authorities were conducting a forensic search on Leib's phone and have alerted police in the Michigan community where he lives.
