A bomb threat at Austria’s largest radio station Ö3 saw 30 police officers searching the broadcaster’s offices in Vienna before giving the all clear on Tuesday afternoon.
An anonymous phone call to Vienna police warned that there was a bomb hidden in Ö3’s offices in Döbling – which are also home to the teletext service and ORF’s online team.
Bomb specialists searched the entire building with sniffer dogs for an hour but found nothing.
Police spokesman Roman Hahslinger said that the phone call was made from a phone box and police are now investigating who made the call.
Austrian police and security services are on high alert after the deadly attacks in Paris last week.
Several newspaper offices and radio stations now have police protection.
On Tuesday evening Vienna public transport (Wiener Linien) also received a bomb threat at around 7pm and police searched the 49 and 52 tram lines as well as the 47a bus in Penzing, and bus stops along the route. Trains and buses were stopped before Waidhausenstrasse station. Shortly after 9pm the all clear was given.
