The din of the first two dance music tracks had drowned out the sound of shooting in which Tobias's colleague, Dan Uzan, had been killed and five police officers injured only moments before, but the adults suspected this was just a story to prevent the children panicking.
"We didn't hear anything," Ms Taboul's husband Yoav, 43, said. "But we could just see in his eyes that something terrible had happened."
So thick were the walls and doors that only one person was able to get mobile phone reception inside the secure room, but this was enough for the adults to learn that the entire Copenhagen district around them had been cordoned off by police.
"We stayed in a small room for nearly two hours. We were very hot, without anything at all," Anat said. "We just sat there and the children were crying and we were taking care of them." Each of the unaccompanied children was paired with an adult, who would look after them.
Two hours later, Tobias returned to help them evacuate safely. Outside, Danish special forces were waiting to drive them to a police station outside Copenhagen, the same place where people evacuated from that afternoon's caf? attack had been taken just hours earlier.
"They had psychologists there to help the children. It was a real crisis situation. It was the same person, who had done it twice in one day," Mr Taboul said. "He said it was the worst day of his life."
Faced with the growing anti-Semitic mood, Jews in Copenhagen had already been taking more precautions. Ms Taboul said she stopped wearing her Star of David necklace after graffiti was scrawled at her son's school last summer.
"Coming to the synagogue, we feel safe normally," she said. "But we always think, 'Maybe something will happen some day,' because there's never any police here." Meanwhile, Israeli Prime Minister Benjamin Netanyahu yesterday urged European Jews to emigrate to Israel for their own security. He said: "Jews deserve protection in every country, but we say to Jews, to our brothers and sisters, Israel is your home. We are preparing and calling for the absorption of mass immigration from Europe."
Denmark's Chief Rabbi Jair Melchior said he was "disappointed" by Mr Netanyahu's stance. But Michael Alt Schuul, 53, a photographer and former volunteer guard at Copenhagen Synagogue, said: "We will have another attack on a synagogue or the Jewish school. I have a child there, but you can't say my children can't go to the only Jewish school, because then you are cutting off your Jewish life.
"My children know that if they hear a shot, they have to fall down on the ground immediately. It's just a part of being a Jew. Other Danes live in a totally other world."
He said he understood what Mr Netanyhau meant: "I do have sympathy - but of course we choose not to live there."
