"Nine fishing boats were seized and 40 Indian fishermen, all from Gujarat, have been apprehended by the Pakistan Marine Security Agency off Arabian sea coast here," Porbandar Boat Association vice-president Manish Lodhari said.
Twenty other fishermen along with a boat were, however, released by PMSA, who will reach here this evening.
The apprehended fishermen would be taken to Karachi, he said.
This is second incident after the killing of one Indian fishermen and kidnapping of 30 others along with the seizure of five boats from international waters off Jakhau coast earlier this month.
