Eleven Indian fishermen have been taken into custody by the Maldivian Navy for allegedly crossing the International Maritime Boundary Line (IMBL), officials said in Chennai on Thursday.

“All are from Kanyakumari district. We are looking into this issue,” District Collector S. Nagarajan told PTI.

The fishermen had ventured into to sea off the Kerala last week and were to return on February 25, 2012 official sources said.
