During the 1970s Tveita Senter struggled with shoplifting, vandalism and drug addicts. In 1979 the board of directors chose to hire Jan Kvalen as its security guard in an attempt to rid the mall of people causing problems. Rather than calling the police, those who were caught shoplifting was often battered in the basement of the mall. Even though the police were aware that a lot of his actions went far beyond what the laws permitted, they chose not to interfere. Kvalen worked at the Tveita Senter for a period of two decades, in which a notorious criminal gang who came to be known as the Tveita Gang ("Tveitagjengen") emerged under his reputed leadership.,
