Suspects in a robbery incident involving the theft of 180 bitcoin mining machines had tied up security personnel on duty before breaking into an aluminium factory to commit the crime.

The suspects, aged 20 to 40, were detained by police, following a report lodged by the owner of an aluminium factory in the West Meru industrial area after his factory was broken into and 180 bitcoin machines were stolen in two incidents on April 27 and May 20.
