This a firsthand account by a Coptic woman named Maria:
I was walking along the sidewalk when I saw Paul, David, and Nabeel walking together towards the area where they were later arrested. Paul and David each had a video camera in hand, when a few young Arabic men approached them. The men were talking to Nabeel, as more people came and surrounded him. Paul and David were both behind Nabeel: Paul to the left, and David to the right. From then on, there were always at least ten people directly surrounding Nabeel. There was one male security guard watching the crowd about 15-20ft behind David. Nabeel was the only one conversing with individuals in the crowd that surrounded him. The crowd, consisting mostly of Arabic males, was expanding. A few women would come and look upon them as well as young boys. A young man came up behind David, said something to him and they conversed for a short time, while David continued taping Nabeel. I walked away to continue on in the festival. Seeing a group of police officers heading toward the group, I returned. A police officer had removed the camera from David and proceeded to handcuff him. I heard David calmly assure, "It's okay. No big deal," while being handcuffed. All three men were escorted out of the group with their hands behind their backs. The police were carrying the cameras that Paul and David had been using. Neither of the arrested men resisted, and were very compliant as they were heading out of the crowd, to where the police had been stationed. People within the crowd were cheering, shouting "Allah hu akbar!" while clapping and shouting. The police continued walking out of the group. When a single man shouted "Jesus is Lord!", one officer who had already passed him, came back and told him to "be quiet". Neither of the officers said anything to the crowd of Muslims that were cheering, while shouting "Allah hu akbar!" After taking Paul, David, and Nabeel to the parking lot where the police were stationed, many security guards had followed and formed two groups. A smaller group of around three security guards were standing closer to the police. A larger group of around five security guards were farther away. Paul, David, and Nabeel were put into a van and taken away.
And here was Richard's account:
I saw Nabeel Qureshi in the midst of a crowd of about twenty teenagers and young adult Muslims. David Wood and Paul were video taping Nabeel and the young Muslims dialog. Police officers, about four, were present acting as a shield protecting Nabeel from a crowd closing in tighter. The entire dialog seemed very peaceful and productive. i did not hear the police officers tell Nabeel or David to stop. The conversation with Nabeel began to wind down. I was able to speak with Nabeel a little to encourage him. At this point the crowd began to break up and the police also walked away. Another young adult Muslim began conversing with Nabeel and the crowd began to come back together. Finally, the police officers returned, about five or six of them, and surrounded David, Nabeel, and Paul. I thought they were going to protect Nabeel and the other brothers, but without warning, the police, rather gently but still forcibly, began taking hold of the camcorders. They arrested all three of the men and escorted them away at the sound of applause by some of the surrounding Muslims.
