Immediately after coming to Goa, all of them ventured into the sea at the Calangute beach in North Goa district - located about 9 km from here - at 6 am, though there were specific signages put up along the shoreline advising people against swimming in choppy waters, Dalvi said.
Five of the tourists got swept away into the waters due to the strong undercurrents. Of them, three drowned while two others managed to swim to the shore, the police said quoting statements of the eyewitnesses.
The three victims were later pulled out from the sea by locals present on the shore.
They were rushed to a primary health centre at Candolim where they were declared dead, the police said.
The deceased were identified as Pritesh Lankeshwar Nanda Gawli (32), his brother Chetan Lankeshwar Nanda Gawli (27) and Ujwal Vakode, who was also part of the group, Dalvi said.
The Goa government had last month issued an advisory asking tourists to refrain from swimming in sea waters along beaches for four months starting from June 1.
This includes a 61-day fishing ban that started from June 1 and ends on July 31.
A firm appointed by the Goa government to provide lifeguards at beaches had recently said that red flags will be put up at beaches in the state to warn people about dangers of wading or swimming in the sea during the monsoon.
