A Trinidadian convicted of two sex crimes and facing seven other charges in the United States, including sodomy, was arrested in New York on Tuesday as part of the United States' Immigration and Customs Enforcement Operation Predator hunt.
By Richard CharanThe man, an accused paedophile, is being held in detention and will be deported to Trinidad.
He was among 50 men arrested.
The detainees were described on a Department of Homeland Security (DHS) website as "criminal alien sex offenders" from 18 foreign countries.
The DHS also reported the deportation last May of a 36-year-old Trinidadian after he served a jail sentence for sex crimes.
He was charged with ten sex crimes in 2002 involving a ten-year-old.
He was charged with sodomy, first degree rape, two counts of sexual abuse and endangering the welfare of a child.
He was convicted on the endangerment and sexual abuse counts and deported.
Deportation of the sex convicts has raised concerns in legal circles.
A senior police source said there was no "official or systematic way" at present to track returning deportees, many of whom no longer have family ties locally.
And criminal defence attorney Brian Dabideen said the law regarding sex offenders to register related only to local convictions.
Act 31 of 2000, an amendment to the Sexual Offences Act 1986 provides for "Notification Requirements for Sex Offenders".
It states that a person convicted of a crime must notify the police in the "local police area" in writing or in person of their name address and birth date.
Police officers said the notification "does not happen" and Dabideen described it as "unenforceable".
He said: "The provisions in that [law] relates strictly to circumstances where people are convicted of sexual offences within the jurisdiction of Trinidad and Tobago. The loophole in the legislation is that it is not mandatory for a person convicted of like offences outside the country to register."
The 20-year-old Trinidadian arrested in New York on Wednesday was convicted of sexually abusing his two nieces, aged three and four, while babysitting them.
Several of the arrested men were from Barbados, Cuba, Dominica, Guyana, Haiti and Jamaica.
