The suspect in the death of Binghamton University student Haley Anderson has been arrested according to two Nicaraguan news outlets.
Anderson, a nursing student at the State University of NY at Binghamton, was from Westbury, Long Island.
The details of how and where Tercero - who's suspected in the murder of Haley Anderson, 22 - was taken into custody were not released.
22-year-old Anderson, of Long Island, was found dead on Friday inside an Oak Street residence in Binghamton.
He was being taken to a prison in El Chipote, which is about 40 miles southwest of the country's capital Managua, ABC News reports.
On Saturday authorities ruled Anderson's death a homicide.More news: Faulty engines: IndiGo, GoAir cancel 50 flights for today

"The investigation determined that the person of interest has left the United States by global air travel flight, prior to the discovery of Haley Anderson's deceased body", police said this weekend in a statement obtained by ABC News.
Broome District Attorney Steve Cornwell said on Monday he will seek a grand jury indictment and, if necessary, present a request for extradition to Nicaragua.
Tercero, Anderson's ex-boyfriend, was also a student at the nursing school.
Tercero apparently does hold dual citizenship. The Nicaragua National Police did not disclose further details about the arrest.
Experts say the Nicaraguan government has refused to extradite certain citizens in previous cases.
