They were taken to the Port-of-Spain General Hospital for emergency treatment.

In May, both local and Venezuelan authorities claimed Mieres, the leader of a criminal gang, was as a key part of a human trafficking network operating between the two countries.
Relatives of migrants who have been missing when they left Güiria on board the pirogue Ana María destined for Chaguaramas, are now pointing fingers at a criminal enterprise headed by the T&T gangster that has been involved in luring women to make the dangerous trip across the Gulf of Paria. They tell stories of women being enslaved, drugged and forced into prostitution.
In September 2017, Mieres, was charged with conspiracy to commit murder Selwyn ‘Robocop’ Alexis, in October 2014. Alexis, the leader of an Enterprise, Chaguanas gang, was murdered in July 2016.
