The 24-year-old suspect was detained near the Azteca Stadium after attempting to reactivate his credential, the city’s Citizen Security Secretariat said in a statement.
A legal representative for World Cup organisers alerted authorities after discovering the online posts. Police did not disclose the fee the man was allegedly seeking for the rental.
Mexico City is hosting several matches during the expanded 48-team tournament, including group-stage fixtures featuring Mexico. Later on Wednesday, World Cup debutants Uzbekistan face Colombia in a Group K match in the capital.
The suspect, who was not named, has been transferred to the public prosecutor’s office, which will determine his legal status, the statement added.
