The group, all men who worked in the administration of a police station, were abducted on a highway in Chiapas.
Security forces in the state of Chiapas, in southern Mexico, are looking for 14 administrative employees of the Ministry of State Security kidnapped by members of an armed group.
The incident happened on Tuesday, about 34.4 km (22 miles) west of the state capital, Tuxtla Gutierrez, on the highway that connects it to the town of Ocozocoautla.
The abductees were all men and worked in the administration of a police station, the state security agency said in a statement.
“Nothing like this has ever happened,” a ministry spokesman told Reuters news agency, adding that the motive for the kidnapping was under investigation.
Federal and state agents are involved in the search.
Some Mexican news outlets released video of the alleged abduction showing several vehicles stopped on the highway with their doors open and men wearing bulletproof vests pointing guns at passengers in the vehicles.
The prosecution said it was investigating the authenticity of the videos, which also showed at least three trucks blocking a highway.
The Reforma newspaper reported that the gunmen took the employees’ mobile phones and ordered them to lie on the ground. The women in the group were allowed to walk freely, he added.
Tuxtla Gutierrez is located approximately 700 km (435 miles) southwest of Mexico City.
During a tour of Chiapas last Friday, President Andrés Manuel López Obrador played down the violence in the region, saying that in general there was “peace, there is tranquility” in the state.
The day before the president’s visit, an official from the attorney general’s office was seriously injured after being shot in Tuxtla Gutiérrez in an attack that killed the person accompanying him.
On June 19, a clash between soldiers and suspected members of organized crime resulted in the death of a member of the National Guard and a civilian in Ocozocoautla.
