GUATEMALA CITY — A member of a U.N.-sponsored anti-corruption commission has been allowed into Guatemala by a court order after he was held for almost a day at the capital's airport.

Guatemala's Constitutional Court ordered the government to admit Colombian Yilen Osorio, who was detained upon arrival at the airport Saturday.

U.N. spokesman Stephane Dujarric said Monday the organization was happy at Osorio's return to Guatemala and expects its government to let commission staffers travel freely.

Guatemalan Foreign Minister Sandra Jovel was due to meet later Monday with U.N. Secretary-General Antonio Guterres.

Guatemalan President Jimmy Morales has sought to end the commission known as CICIG, which has investigated Morales' son and his brother. They deny accusations of corruption.

Morales refused to renew CICIG's mandate last year and barred its chief from returning to Guatemala from a business trip.
