The whole thing looks pretty confusing to me. As stated in the first post in the thread, made by Icon, there seem to have been two arrested groups--one group arrested in late 2014, and one group arrested last month. Below are excerpts from one apparently American article (added to this post by edit), one Chinese article, and several Kenyan ones, followed by one CCTV (China) YouTube news clip and two NTV Kenya ones.
This excerpt, concerning the 2014 arrests, seems to have been at least partially taken from an interview of one of the detainees, from an article in Quartz, which is apparently an American digital publication:
--Lily Kuo, "The strange case of 77 blue-collar Chinese migrants that Kenya is calling 'cyber-hackers,'" Quartz Africa, November 20, 2015

This Chinese newspaper article from late 2014 gives the impression that the 2014 detainees were engaged in a conventional sort of telephone fraud:
--"China strongly supports Kenya combating criminal activities in all forms," China Daily, December 11, 2014
chinadaily.com.cn/world/2014 ... 067804.htm
But with regard to those same late-2014 arrests, a Kenyan article seems to give the impression that the first group was up to something more:
--"77 Chinese held in cyber bust," Daily Nation (Nairobi, Kenya), December 11, 2014
nation.co.ke/news/77-Chinese ... index.html
From the Kenyan articles, so far it has been difficult for me to tell how many detainees are Taiwanese and how many are Chinese.
--"Chinese cyber fraudsters ‘setting up base in Africa,’" Daily Nation, December 7, 2014
nation.co.ke/news/Chinese-cy ... index.html
Regarding the 2014 incident, I got the impression that at first, Kenya was not enthusiastic about turning the detainees over to China.
--"China pushes Kenya to hand over suspects linked to cyber fraud," Daily Nation, January 15, 2015

The second group, arrested last month, appears to have been arrested in the same area of Nairobi as the 2014 group.
--"41 foreigners caught illegally installing powerful communications equipment in Nairobi," Standard Digital (Nairobi, Kenya), April 8, 2016 standardmedia.co.ke/article/ ... in-nairobi
This is about the 2014 arrests, from CCTV, Chinese television news:
This is also about the 2014 incident, from NTV Kenya, Kenyan television news:
This is from NTV Kenya, on last month's arrests:
So far I haven't been able to find a CCTV YouTube item on last month's arrests; I've only been able to find CCTV items on the deportations. I'm not saying that that there are no CCTV news items on YouTube about the 2016 arrests. The arrests could be covered in the clips about the deportations, which I didn't check.
