The victim, 20-year-old Karen Lojore, was reportedly crushed on Saturday near a gate into the Nyayo National Stadium amid long queues and delays worsened by heavy rain, with other fans being injured. Family and friends of Ms Lojore have called for a full investigation and justice for her, with Kenyans on social media expressing their sympathies. In a statement posted on Instagram on Monday, Asake said he was "devastated by the tragic incident". Kenyan police spokesman Michael Muchiri told the BBC that investigations were ongoing.

"My heart goes out to the family, friends and loved ones of Karen Lojore," Asake said, pledging to support efforts to "understand what happened". He said music was always his "way of sharing love and joy" and "it breaks my heart that anyone had to experience such loss". "Those responsible should be held accountable," he added. In a social media post tagging the concert organisers as well as Asake, a woman believed to be Ms Lojore's mother wrote: "What happened to my child? Why her? I want justice for my child."

The organisers of the event, Tukutane Entertainment, said they were working with the authorities to "understand what happened". The police spokesperson has said the "incident is being looked into comprehensively so as to give answers as to what, how and why it happened.... and ultimately avoid such a scenario in the future". A journalist with Kenyan broadcaster Citizen TV, Immanuel Ndungu, who attended the concert, spoke on Instagram about problems with the stadium entrance, crowd control and how people were allowed in. Tukutane Entertainment has organised several big concerts in recent years, including shows by African music stars Tems, Rema, and Sauti Sol. (BBC)
