Former Mexican lawmaker Juan Antonio Vera Carrizal is under arrest for allegedly ordering the acid attack on a saxophone player last September.
Oaxaca state police say Vera was the main suspect in the case, where acid was thrown on saxophonist María Elena Ríos Ortiz by a man pretending to be a customer at the travel agency where she worked.
Reuters news agency said Ortiz believed her ex-boyfriend was behind the attack.
The motive for the attack on Ortiz was not clear.
Interpol has reportedly arrested a second man in connection with the crime, which is part of a disturbing trend of violence against women in Latin America. Women’s rights activists say there have been more than a dozen cases of acid attacks in Mexico over the past decade.
