Tripoli , Libya ( CNN ) -- Two Gadhafi loyalists and one National Transitional Council fighter were killed Friday in the Abu Salim neighborhood of Tripoli , an NTC member told reporters . A group of about 10 Gadhafi loyalists had entered the streets of Abu Salim waving green flags and holding a picture of the ousted Libyan leader in a move to draw NTC fighters into the neighborhood , which has remained largely loyal to Gadhafi , council member Abdelrazaq Al Aradi said . When anti-Gadhafi forces responded by entering the streets , the loyalists opened fire , Al Aradi said . Afterward , Omar Khadrawi , the assistant to the interior minister , directed a message through reporters to any remaining loyalists . `` Their names have been discovered and the information about them receiving weapons is in the hands of the security now , '' he said . He added that he was offering them `` a last chance '' to hand in their weapons to authorities . On Friday evening , the mood on the streets of the capital was tense . Heavily manned checkpoints dotted the streets en route to Abu Salim . Fighters and area residents told CNN that a small number of Gadhafi supporters started looting and burning cars after Friday prayers . NTC fighters , some drawn from other neighborhoods , responded quickly . Witnesses and fighters said a number of Gadhafi loyalists were detained . Reports conflicted on whether they were armed . Later in the evening , gunshots could be heard in a number of neighborhoods in the city . Al Aradi told CNN separately that NTC fighters think they have captured the organizer of clashes Friday in the Tajoura neighborhood of eastern Tripoli . On Friday , the U.N. human rights office raised the issue of the number of prisoners in Libya and their treatment . `` It could be up to 7,000 , '' said Mona Rishmawi , a senior official with the group in Geneva , Switzerland . `` At this stage , there is no police infrastructure , there is no prison authorities . The prison authorities were under the Justice Ministry and , right now , the Justice Ministry is not fully functional . '' `` There is allegations and evidence of torture '' in the prisons , she said , citing lawyers , clients and human rights groups . CNN 's Raja Razek and Ingrid Formanek contributed to this report .
