According to data collected by the authorities, it was around 11 pm that the report was received by the Police Station in Guadalajara of gunshots in the vicinity of the Consulate.
When police arrived, they were told that it had been a false alarm and firecrackers in the area.
However, Saturday morning it was confirmed that an assault had occurred with fragmentations from grenades found on the Consulate grounds, so the Federal Public Prosecutor was notified.
The consulate in Mexico’s second biggest city said via Twitter that the office was closed because of what it described only as a “security incident” Friday evening. The tweet gave no details, though it said nobody was injured. It said U.S. officials are also investigating.
The consulate says it will provide more information as it becomes available, including whether consular operations will be available Monday.
Neither Mexican officials nor the consulate alluded to possible suspects in the incident.
Military personnel, from the Prosecutor’s Office and the Police of Guadalajara were dispatched to protect the area.
