Front Line is deeply concerned following reports that the Bahrainian authorities have refused to disclose the whereabouts of human rights defender, Mr Abdul-Redha Hassan Al-Saffar, who was arbitrarily arrested, early in the morning of 21 December 2008, from his residence in Mahooze village by state security forces despite there being no arrest warrant against him. No reason has been given for his arrest and his whereabouts are as yet unknown.
