Ewold Horn, a bird spotter from Groningen who was abducted by terrorist organization Abu Sayyaf in the Philippines in 2012, is still alive and in good condition, according to a recently freed captive. The 28-year-old man, Jelster Ed Quimbo, was released by Abu Sayyaf on Sunday, Philippine news site Philstar reports.

Ed Quimbo told the authorities that he was held captive along with a Dutch national, a Vietnamese national and three Filipinos. He said that the other hostages were in good condition.

Horn was abducted with a Swiss person while bird spotting on the island of Jolo in 2012. No contact has been had with the man since. Horn's Swiss counterpart was rescued by the military in Patikul in December 2014, according to the news site.
