Mexico City, Jun 8 (IANS/EFE): Businessman and politician Juan Ignacio Torres Landa was among four people killed Friday when a helicopter crashed in the central Mexican city of San Luis Potosi, the governing Institutional Revolutionary Party, or PRI, said.

A fifth person was injured in the accident.

"The death of Torres Landa was confirmed by his family. We spoke with his wife and she told us," Adalberto Valadez, PRI spokesman in the businessman's home state of Guanajuato, told EFE.
