Homeland Security Minister Roger Alexander says police have been placed on “high alert” with respect to nationals repatriated from the United Kingdom who have allegations of murder and gun-running against them.

Minister of Foreign and Caricom Affairs Sean Sobers told the Express on Monday that hundreds of Tri­nidad and Tobago nationals who travelled to the UK and applied for asylum had been repatriated.

Sobers said between 90% to 97% of the 700-plus nationals who had sought asylum had been returned to T&T in the past couple months.
