Prominent Bahraini human rights activist Nabeel Rajab has been released from prison on bail, following a seven-month pre-trial detainment over a series of tweets, but was ordered back into custody over separate investigations.
From daily The Morning Star in Britain:
Bahrain: Jailed rights activist denied bail over tweets to reporters
Thursday 29th December 2016
BAHRAINI rights activist Nabeel Rajab, due for release on bail, had the bars slammed shut on him again yesterday.
Prosecutors said that the Bahrain Centre for Human Rights president should remain in detention over separate allegations.
Mr Rajab has been held in custody for seven months after tweeting about the Saudi Arabian war on Yemen and describing torture in Bahraini prisons. The despotic British-backed kingdom wants to jail Mr Rajab for 15 years for the tweets.
While he was due to get bail for this “offence,” it appears that prosecutors were not happy with him sending letters to foreign newspapers.
Underscoring the ludicrous nature of the charges against Mr Rajab, they announced his continued imprisonment on social network Instagram.
