Mexicans held

Three members of Mexico's top police force were arrested including one for involvement in the killing of a Roman Catholic cardinal, the Attorney-General Jorge Carpizo said, Reuter reports from Mexico City.

One of the men, whom he identified as Commander Garcia of the Federal Judicial Police, 'was at the scene supporting one of the contending drug gangs' when Cardinal Juan Posadas Ocampo was shot dead in a gun battle two weeks ago, Mr Carpizo told a parliamentary commission.

After his arrest Mr Garcia provided information on two other police officers involved in drugs and corruption, he added.
