Twitter campaign seeks missing Chilean student

Using the hashtag #letsfindcarlos, his friends and family are hoping to find out what happened to Carlos Gallardo Ramirez, who had come to Europe to study as part of an exchange programme at the Spanish University A Coruna in Galicia.

His mother says that he went missing in mid-August and that his last known location was Vienna.

Even the Spanish actor Antonio Banderras has joined the campaign, with friends of Ramirez also appealing to Austrian Arnold Schwarzenegger to draw attention to the young man’s strange disappearance.
