BBC Report: "... The students all attended a teacher training college in Ayotzinapa with a history of left-wing activism, and their presence in Iguala raised alarm bells with the local authorities. When the students boarded busses to return to their college, they were stopped by police - allegedly on the orders of Mayor Abarca. The officers opened fire and killed three students and three people in nearby vehicles. They stopped one busload of students trying to flee and took them to a local police station. ..."

Jose Luis Abarca, who was mayor in the town of Iguala when the students disappeared in September, was apprehended in Mexico City by federal officers along with his wife, Maria de los Angeles Pineda, Jose Ramon Salinas said on his Twitter account. Both Abarca and Pineda are suspects in the disappearances, Attorney General Jesus Murillo said last month.
The detentions mark a milestone in a case that has sparked protests by tens of thousands, pushing President Enrique Pena Nieto to vow to bring the perpetrators to justice. Federal authorities investigating the disappearances say the students were handed over by local police to a drug gang in Iguala after they tried to disrupt a public event held by Pineda.
