Both events were filmed by the bystanders, publishing the murders on the internet. In spite of this mass of evidence, the local justice took two years of investigation to finally convict 4 members of the mob to lifetime imprisonment and 6 others to shorter sentences; 26 suspects in custody were released without charge as well as the two police officers. A local politician, Joseph Yoland, was accused of inciting the killings on his radio station at the island, but the charges were dropped when the court allegedly was unable to retrieve any recordings of the aired shows that evening. Following the events, the French authorities warned travellers for "high risk of assaults, that could be extremely violent", U.S. travellers are also advised " be aware of the potential for mob violence and ‘popular justice’ that is sometimes directed towards foreign nationals.". The lynching in Nosy Be is a rare public murder of expatriates in Madagascar; most lynchings concern locals. However, expatriates are frequently subject to kidnapping and extortion, such as the January 2015 kidnapping of a 12-year old French child outside of his school, and two separate kidnappings of French citizens of Indo-Pakistani origin in April 2016 that triggered the intervention of the French police tactical unit GIGN in Madagascar.
