About 20 Pakistanis were arrested and their three boats seized by the Indian Coast Guard off the Okha coast in Jamnagar district of Gujarat on Friday.
According to the Coast Guard sources, the Pakistanis were held for illegally entering the Indian territorial waters by the Coast Guard's patrol boat Mirabai.
They were brought to the Okha port for joint questioning by police and intelligence agencies to determine their identity, particularly whether they were genuine fishermen, and their reasons for entering the Indian territorial waters, the sources said.
