Stockholm, Muharram 13, 1438, Oct 14, 2016, SPA -- Swedish police searched Friday for a man wearing a clown mask and a yellow jacket who stabbed a person in southern Sweden, the latest incident involving adults in creepy outfits, while in neighboring Norway, a toy store chain decided to stop selling clown costumes. Police spokeswoman Ulla Brehm says there have been two similar incidents where people dressed like clowns stood outside schools and "scared children. This is not a crime as such but very, very unpleasant," AP reported. Brehm says the incidents "likely had spread via social media from the United States," adding "it is not funny when people are being scared." She said Friday a 19-year-old man was stabbed late Thursday with a knife in the shoulder in Varberg, south of Goteborg. He sustained superficial wounds and despite searches, the attacker has not been found. Similar incidents were reported elsewhere in Sweden, Denmark and Norway, where the Ringo toy store chain decided to stop selling clown costumes in its 114 shops. --SPA 16:58 LOCAL TIME 13:58 GMT www.spa.gov.sa/w
