A federal judge in Mexico has ordered that former Iguala police chief Felipe Flores be held on charges of kidnapping in the disappearance of 43 students.

The Attorney General's Office announced the judge's order in a brief statement late Tuesday.

Relatives of the 43 missing students from the Teacher's Training College Ayotzinapa Raul Isidro Burgos take part in a march to protest against the government's handling of the investigation in the case of 43 students, to mark the 19-month anniversary of their disappearance, in Mexico City, Mexico, April 26, 2016.

National Security Commissioner Renato Sales said earlier Tuesday in an interview with Imagen Radio that Flores hasn't provided any information about the students' location.

The government's investigation determined that local police in Iguala intercepted several busloads of students from the Rural Normal School at Ayotzinapa on Sept. 26, 2014. They were allegedly turned over to a local drug cartel and killed.

Flores was arrested Friday in Iguala. Sales says he was caught visiting his wife at a friend's house.
