Mexican authorities have arrested a former college professor who was on the FBI's 10 most wanted list over allegations of child sex abuse.
Walter Lee Williams was detained late Tuesday, Mexican state news agency Notimex reported.
The FBI placed the former university professor wanted for alleged sexual exploitation of children on the list Monday, according to Notimex.
Williams researched in the field of gender development at a university in California, which gave him easy access to his victims, mainly teenage boys in developing countries, the FBI said.
One of the FBI's Ten Most Wanted fugitives was picked up Saturday in Nicaragua, according to a federal law enforcement official.
The official did not provide details on how Eric Toth, 31, was located and apprehended. Toth is a former Washington private school teacher who was wanted on child pornography charges.
According to the FBI, in June 2008, images of child pornography were found on a school camera Toth had been using. He allegedly also produced such images in Maryland.
U.S. officials are working on returning him to the United States to face charges.
Toth was put on the Ten Most Wanted list in March 2012, and there was a reward of up to $100,000 for information leading to his arrest.
A short video released by the FBI on Thursday shows two suspects in Monday's Boston Marathon attack walking single file on a sidewalk along the race route.
The video was released Thursday as investigators asked for the public's help in identifying the two men.
One of the two suspects in the Boston Marathon bombings left a bag believed to contain one of the explosives outside the Forum restaurant on Boylston Street in the city, FBI Special Agent in Charge Richard DesLauriers said. The bag was dropped there "within minutes" of the explosions, he added.

That suspect appeared Thursday in federal court in Oxford Mississippi.
During a four-minute hearing, Magistrate Judge S. Allan Alexander ordered Paul Kevin Curtis - who appeared in court with attorney Christi McCoy - to remain in custody until a grand jury issues an expected indictment and a preliminary and detention hearing on April 29.
Earlier Thursday, the 45-year-old resident of Corinth, Mississippi, was charged with sending a threat to the president.
A criminal complaint charged Curtis with "knowingly depositing for conveyance in the mail and for delivery from any post office any letter, paper, writing or document containing threats to take the life of or to inflict bodily harm upon the President of the United States."
The federal complaint further charges him with sending "communications addressed to other persons, and containing a threat to injure the person of others."
