A Trinidad law group says it has "grave concerns" about a bill that would legalize limited wiretapping to catch criminals.

At present, any wiretapping to intercept phone calls and other communications is outlawed in the Caribbean nation.

Prime Minister Kamla Persad-Bissessar says the legislation is needed to allow to serve in "limited circumstances as a weapon in the fight against crime."

In a statement Thursday, the Law Association of Trinidad and Tobago says it is worried that law-abiding citizens could be "open to abuse" if lawmakers pass the bill introduced last week by the prime minister.
