Mexican police arrested two people allegedly tied to the murder of four relatives of a Mexican marine who died in a gun battle with a drug-gang boss and his bodyguards last week, a state official said.

Authorities from the southeastern state of Tabasco will offer more details on the arrests later today, said a spokeswoman for the state attorney general’s office, who can’t be identified because of government policy.

The people arrested are suspected of being hit men for the drug cartel run by Arturo Beltran Leyva, the alleged kingpin killed in last week’s gunfight, El Universal reported on its Web site, citing Rafael Gonzalez, the state’s prosecutor. The arrests were made in a hotel in Tabasco, the newspaper reported.
