The boy's mother had left him at a friend's house, where he apparently didn't stay long, police reported on Friday. During his foray through the Oesede district of Georgsmarienhütte, he managed to boost a €600 go-kart, taking it on a wild tour of several kilometres.
The youth stole toys from a number of stores along the way, stashing his loot in the go-kart's boot. He then stepped-up the pillaging, acquiring a trailer and stealing a total of €350 in toys, police said.
Witnesses noticed the boy around late afternoon and contacted police. The seven-year-old was finally handed over to his parents at the police station.
