Son of the late Ya-Na Yakubu Andani II says he is disappointed with government for failing to successfully prosecute alleged killers of his late father.According to Mohammed Yakubu Andani the National Democratic Congress before coming to power promised them justice and only justice is what they will settle for.His remarks follow a ruling by the High Court which acquitted and discharged 15 suspects charged with the 2002 violent incident in Dagbon which led to the killing of the late Ya-Na Yakubu Andani II and a number of his elders.The ruling has provoked yet another violent incident with the Andani youth going on rampage, destroying properties of the ruling party in Tamale. One person has died as a result of the riotous incidents.Speaking to Joy News’ Israel Laryea on Thursday, Mohammed Yakubu Andani accused the NDC of deception.He said during the 2008 campaign, the NDC promised the people of Dagbon it had incontrovertible evidence to prosecute the alleged killers and wondered why they will lose such a high profile case in court now that they are in power.He explained the recent violent scenes that followed the ruling were as a result of people’s disappointment with government.“Government has disappointed all sympathizers and relatives of the Andani side. Right from that campaign - from the president to the last person in the NDC - they said everything about Dagbon. They assured us that they had all the evidence to arrest and prosecute any human being involved in the murder of the Ya-Na and his elders. So today you sit down and lose this way. Definitely people will not be happy," he said.He maintained it was based on the promise by the NDC that majority of the people in Tamale voted for the NDC and has charged “the government to come out and come out well” or “we will come out and know what to do.”He would not say what he meant by they will come out if government fails to produce the killers, except to say “that is left to us. We can’t make it public now.”He said the family respects the court’s decision but hinted they will use every acceptable means possible to seek justice.
