Police in Austria may have missed a chance to capture one of the world's most wanted men last year.
Officers apparently questioned war crimes suspect Radovan Karadzic during a raid on a flat in Vienna while looking for a Serb man suspected of murder.
When the officers saw images of Karadzic after his capture this week they recognised him as the man from the flat and contacted the Interior Ministry, an Austrian newspaper said.
According to local reports, the fugitive had been living in the apartment for around three months.
Police are believed to have encountered Karadzic when they raided the apartment of the girlfriend of a Serb man suspected of having shot dead another Serb in a Vienna cafe in May 2007.
When the police asked him to identify himself, he is reported to have shown a Croat passport under the name 'Petar Glumac', and explained calmly that he was in Vienna for training.
The Austrian Interior Ministry confirmed the raid, which took place on May 4, 2007, and said policemen who took part in it recognised Karadzic as the man they saw in the apartment when they saw his pictures after his capture.
Karadzic, who vanished in 1996, was captured in Belgrade earlier this week disguised as a doctor.
Serb authorities said the 63-year-old, who had been indicted for genocide during the Bosnia wars, was barely recognisable in his white long beard.
