Four filmmakers arrested in connection with the production of BBC's Blood Parliament documentary have been released on free bond, following public outcry.

Nicholas Wambugu, Brian Adagala, Chris Wamae, and Markdenver Karubiu were arrested on Friday at their studio in Karen, Nairobi, and later detained at Pangani and Muthaiga police stations.

Their equipment is, however, still withheld.  The arrests sparked widespread criticism on social media, with many questioning the grounds for their detention.

Law Society of Kenya advocate Ian Mutiso said the four were held for more than 24 hours without formal charges. "They were accused of publishing false information, but we are yet to get the particulars; it seems they are being targeted in connection with the airing of Blood Parliament by BBC," said Mutiso.
