Dan Zethraeus, an inventor and television director for Swedish public broadcaster Sveriges Television, said he encountered police barricades while returning to his car Tuesday in Copenhagen and went to wait in a local cafe, where a Swedish reporter called him to ask why his car was at the center of a terrorism alert, The Local.se reported Tuesday.
"I rushed off to the police and explained that it was an invention," Zethraeus said. "The bomb squad smiled a bit and weren't particularly upset, but the police were quite tense."
Zethraeus said he had been driving the modified car around Sweden for about a month without raising any suspicions.
The Copenhagen Post reported the wires are designed to recover electricity as the car moves.
