One of three aid workers kidnapped in Somalia has been taken into police custody, the Danish Refugee Council announced Wednesday.

The worker, a Somalia man, has been in custody since Tuesday. Danish officials said "his role in the incident will be further investigated," without offering further details.

The whereabouts of the two other aid workers, a 32-year-old American woman and a 60-year-old Danish man, are unknown.
         
The three are employed with the Danish Refugee Council, a group that helps dispose of unexploded bombs and teaches communities about the dangers of land mines.

"Somalia and the rest of the Horn of Africa is in the midst of a humanitarian crisis. People are in acute need of relief aid and it is quite tragic that we are targeted like this," said Ann Mary Olsen, head of the Danish Refugee Council's international department.

An official said it's likely the missing aid workers have been taken to a former pirate stronghold on the Somali coast and are being held for ransom.

These latest kidnappings come only weeks after two women working for Doctors Without Borders were taken from a refugee camp in neighboring Kenya.

Somali gunmen were also suspected in those attacks.
