SOME 2,000 workers have been told they can return to work following an alleged bomb threat on a skyscraper in Madrid.
According to ABC, the supposed threat against the Australian Embassy inside the Torrespacio tower was a false alarm.
Sources told the newspaper the threat may have been caused by the triggering of a fire alarm.
Police, who are remaining on site, are investigating the events after carrying out a search for explosives with sniffer dogs.
The building, which also houses the British, Canadian and Dutch embassies, is one of the four towers of the Paseo de la Castellana.
