According to the study, the main types of Boda-Boda related crimes prevalent in Changamwe Sub-County were robberies, thefts, kidnappings, murders and other forms of gun violence. One of the major perceptions of emerging security threat is that of motor bike related gang that has increased vulnerability of many businesses and targets due to their disguised surveillance on unsuspecting victims and targets. According to the study Boda-Boda related crimes are largely under regulated. As one of the major policy concerns, concerted efforts by the Government and the Private sector to come up with preventive social programmes such as economic empowerment and alcohol and drug control programmes that will potentially avert the identified pushing factors responsible for rampant Boda-Boda sector related crimes; Poverty and alcohol consumption and drug use.
