Take the bear in Florissant, Colorado, captured breaking into a car. His motive was probably theft; the possibility he wanted to steal the car and use it run over an ursine ice skating instructor can not be ruled out.
More disturbing is the case of Juan the Andean spectacled bear, resident of a nice zoo in Germany. After crossing a moat using a log for a raft, Juan climbed a wall and "went straight for [a] playground" full of children. Cut off by zookeepers, he attempted to flee on a stolen bicycle.
