Police in the eastern Mexican state of Veracruz have arrested five people suspected of involvement in the murder of the daughter of a Congresswoman.
Valeria Cruz Medel, a medical student, was shot dead while working out in a gym in Ciudad Mendoza on Thursday.
Carmen Medel broke down when she found out about her daughter’s murder during a session of Congress.
Investigators said they believed Ms Cruz was killed by a gang in a case of mistaken identity.
Murder rates in Mexico reached a record high in 2017 with official figures suggesting that more than 25,000 people were killed that year.
Non-governmental groups say that 2018 could top even that figure.
Footage of Carmen Medel sobbing and shouting in the Chamber of Deputies after she received a phone call informing her her daughter had been killed made news in Mexico.
Fellow lawmakers rushed over to console Ms Medel and the session was later suspended.
