(Vancouver, WA) -- Vancouver Police are warning residents about the "Door Kick Challenge." It's gaining popularity on the app TikTok. On Wednesday, it happened at least seven times in Vancouver in less than an hour. Under the challenge, people kick in the doors of unsuspecting people and then run. Surveillance video from attacks in the Hearthwood Neighborhood in East Vancouver showed the suspects using an older, dark colored four door sedan with chrome spoke wheels. Police are urging parents to talk with kids about the dangers of the crime.
