A family of five, including three children, from Sri Lanka illegally arrived in Rameswaram early on Wednesday.
Police identified them as S. Shanthakumar (33) of Vavuniya, his wife Rupa Leshmi (26) and their children Hemsran (7), Yoshana (4) and Darushan (2).
The family had boarded a mechanised boat at Thalaimannar in the island nation and reached Arichalmunai at around 3.30 a.m. They were rescued by the Marine Police in Rameswaram and taken to the police station for an inquiry.
A total of 227 Sri Lankan nationals have arrived in Rameswaram since a severe economic crisis hit Sri Lanka. They have been lodged at the Sri Lankan Rehabilitation Centre in Mandapam.
