Vietnam today (28) sent home 151 Sri Lankan illegal immigrants who had been caught attempting to go to Canada by the sea route.
They were among those housed in a Vietnamese refugee camp before their repatriation.
The 142 men and nine women were handed over to the CID for investigation upon their arrival at Katunayake Airport.
Immigration Department spokesperson Hansika Kumarasinghe said another group of Sri Lankan illegal immigrants are still being kept in Vietnam.
