Vienna police say they've arrested three suspected drug dealers and seized cocaine with a street value of 400,000 euros ($446,000).

Police in the Austrian capital said Sunday that the three men, aged 51 to 55, were arrested on Aug. 16 as they tried to sell more than 5.5 kilos (over 12 pounds) of cocaine.

They didn't give further details of the suspects, but said the arrests were conducted in cooperation with Croatian authorities. The suspects are in custody and refusing to answer questions from authorities.
