Somali Pirates: Iranian Fishing Boat Captured?

I think that's what this report means here:

Somali pirates in the northern semi-autonomous region of Puntland have hijacked an Iranian vessel, Press TV has been informed.

According to Press TV's correspondent, Somali pirates seized the Iranian vessel for illegal fishing carried out without the permission of the Puntland Administration.

Meanwhile a maritime official at the East African Seafarers Assistance Program Andrew Mwangura told Reuters on Wednesday that the ship was reported as seized on Monday.

"I hear that the villagers have taken it because of fishing illegally or for damaging fishing equipment," Mwangura said. "Vigilantes usually move when you destroy their nets or boats and hold the ship until they are paid back."

The Iranian Foreign Ministry, however, has not yet confirmed the report, saying that it is still under investigation.

In most parts of the world, that would be called "arresting" the vessel for illegal fishing.
