An obsessed German mega-fan who allegedly stalked a singer from “The Voice” claims he was wrongly arrested — and is suing the object of his affection for $5 million.

Stefan Dameron was arrested in Manhattan on Aug. 31, accused of stalking singer Ivy Quainoo, 22.

He showed up at her dorm in October 2015 and six months later approached her friend, saying “Take me to Ivy now!”

Dameron spent a month at Rikers. The case was later dismissed and sealed.

He’s now accusing Quainoo, her pals and the city of libel, slander and false arrest in Manhattan Supreme Court papers.

Lawyer Daniel Tessler says what Dameron did “doesn’t come close to constituting stalking.”

Quainoo declined to comment. The city Law Department will review the complaint, a spokesman said.
