Mexico City  - No one was injured in the hijacking of a airliner, in an incident that ended about an hour after the plane landed Wednesday in Mexico City.

The Bolivian hijacker, who had lived in Mexico for 17 years, told police that he hijacked the plane to press his demand to speak with Mexican President Felipe Calderon.

The suspect said that he wanted to alert Calderon to the risk of a major earthquake, because Wednesday was the ninth day of the ninth month of the ninth year of the 21st century.

"Christ foretold evil," the suspect, identified as Jose Marc Flores Pereira, said as he was presented to the media later Wednesday. "Mexico is the light."

Mexico's Federal Public Security Minister Genaro Garcia Luna said that the attacker had not been carrying any weapons or explosives, and that the claimed bomb that he showed a flight attendant was bogus.

The hijacker was said to have a criminal record in Bolivia and appeared to be under the influence alcohol and perhaps other substances.

The Aeromexico plane, a Boeing 737 carrying 104 passengers, was flying from Cancun, the seaside resort city in south-eastern Mexico. According to released passengers, it was hijacked shortly before landing at the Mexico City airport.

Garcia Luna said that it was the flight captain who convinced the hijacker to surrender. He was in touch with both the control tower and the hijacker, who never made it inside the cockpit.

Following negotiations, the attacker released most of the passengers. Federal police then stormed the plane and detained at least six other men as well as the hijacker.

Garcia Luna explained that the attacker had said that three men were involved in the action and that authorities needed to confirm that the man had acted alone. However, the suspect later told police that he had said that because the Holy Trinity was with him.

After landing, the aircraft remained isolated on a runway far from the airport's main building until the hijacking was resolved.

Passengers only learned of the hijacking after the plane landed.

The hijacker looked like "a normal, well-dressed passenger," Rocio Garcia told Mexican television after her release. "We did not immediately know what happened. It was all confusion, and then they told us that the plane was being hijacked by one person."

Adriana Romero, another released passenger, had a different perspective and saw no panic. "When we landed we were told to remain seated," she said.

At the time, passengers were told that the plane was being hijacked and that negotiations were ongoing, Romero said. She described the hijacker as prosperous-looking, wearing a "good watch, a good shirt."

"He often stood up to take things out of his suitcase," Romero said.
