A Mexican mayor accused officers from his own police force Wednesday of trying to kidnap him in a gang-ordered attack that left eight people dead, including a child and a pregnant woman.

Inde Mayor Ernesto Nunez told reporters that he lodged a complaint against municipal and Durango state police officers, accusing them of involvement in Sunday’s kidnapping attempt alongside mafia hitmen.

“We already knew that all municipal police were corrupt, and state police can be corrupt too,” he said.

Nunez, whose town of 4,800 people is located in the northwestern state of Durango, said his family, workers and veterinarians were in his ranch when the gunmen fired several rounds and lobbed grenades at it.
